Introduction Back to top

Wrye Bash is a powerful mod management utility for games based on Bethesda's Creation Engine. Its features include:

It currently supports the following games:

Wrye Bash can appear daunting at first. To help make it more manageable, the documentation has been split into a few readmes that are targeted towards different usage requirements.

This readme covers only the most commonly used features, so that the average user can start using Wrye Bash without being overwhelmed. Information on the less commonly used features and more technical details of the features covered in this readme may be found in the Advanced Readme. Information on some of the syntaxes and file formats that Wrye Bash uses are found in the Technical Readme. Finally, Wrye Bash's version history is stored in the Version History document.

Glossary Back to top

Modding for Creation Engine games has a wonderful history of confusing terminology. The list below details some terms commonly used when dealing with mods.

This readme will also use the placeholder [Game]. Replace this with the game that you're managing with Wrye Bash. Additional terminology specific to Wrye Bash's functions will be introduced as required. Also, links that are followed by External Link Icon go to pages that are not part of the Wrye Bash documentation.

Installation Back to top

The simplest way to install Wrye Bash is using the installer, as it installs Wrye Bash and its dependencies automatically. Note: If you want to manage a Windows Store game (since the installer does not and cannot support Windows Store games) or prefer to manually install Wrye Bash for any other reason, read the instructions below.

Note: There are two versions of Wrye Bash available: the Python version and the Standalone version. Both are the same program, but the Standalone version has fewer dependencies and so is recommended for most people.

Windows Vista, 7, 8 & 10 users: Windows' User Account Control feature may interfere with the running of Wrye Bash and other utilities. See the File Permissions section for solutions.

Manual Standalone Version Installation:

  1. Download and install the latest MSVC Redistributable (x64).
  2. You now have a choice:
  3. Run Wrye Bash by double-clicking Wrye Bash.exe in the new Mopy folder. If you chose the second option above, Wrye Bash will now open. However, you will have to repeat the procedure for each new game you install. If you chose the first option, you will see a game select screen. Simply select one of the listed games to continue:

Manual Python Version Installation:

  1. Download and install all the required Python libraries and python itself. See the Python Components section of the Advanced readme for the list of included libraries and their versions. If you have previously installed Python and any Python libraries, you may not need to install them again.
  2. Download and install the latest MSVC Redistributable (x64).
  3. Extract the downloaded Wrye Bash archive into your game folder (e.g. Oblivion, Skyrim or Fallout, depending on the game) so that the Mopy directory appears by the game executable. See the Alternative Install Locations if you wish to install to a different directory.
  4. Navigate to the Mopy directory and run Wrye Bash by double-clicking Wrye Bash Launcher.pyw.

Uninstallation Back to top

The ease with which Wrye Bash can be removed is dependent on how much you use it to manage your modded game.

If none of the above points apply to you, or once you have taken the necessary measures for the points that apply, you can uninstall Wrye Bash by either running the uninstaller, if you used the installer to install Wrye Bash, or delete the following files and folders if you installed it manually.

Installing Mods Back to top

Overview Back to top

Wrye Bash's Installers tab.

Wrye Bash mod installer are known as BAIN (BAsh INstallers), and are presented on the Installers Tab. The first time the Installers tab is opened, a dialog will appear asking if BAIN should be initialized. If you click Yes, BAIN will be initialised, which can take some time. After that, the information refresh performed when the Installers tab is opened is much faster.

BAIN's primary function is to install mod packages. BAIN Packages can be compressed archives (.zip, .7z, .rar, .001 or .tar) or uncompressed directories called projects. When we refer to projects and archives together we will also be using the collective term packages or installers.

If BAIN is disabled, i.e. if you clicked No on the dialog that was displayed the first time you selected the Installers tab, it can be re-enabled by right clicking on a column header in the Installers tab and selecting Enabled.

Packages need to be placed in the Bash Installers directory which is created the first time Bash runs inside the "Game" Mods directory. This directory is by default created on the same level as your game directory (that is, if your game exe is located in "C:\GAMES\TESIV\Oblivion", then by default Bash will create the "C:\GAMES\TESIV\Oblivion Mods\" directory on first run), but you can point Bash to create this "Game" Mods directory wherever you want (or point it to an existing one) via the sOblivionMods ini setting. Do not however put it inside the game Data directory, as the game may well be confused and scan it adding to performance deterioration, mods thrashing.

To add an installer to Wrye Bash Installers, you can either manually copy and paste the zip to the Bash Installers Directory, or just drag and drop the zip onto the Installers tab.

Bash will scan the Bash Installers directory and pick up all subfolders and all archives - except for:

  1. folders or files that begin with -- will be skipped
  2. a Bain Converters subdir of Bash Installers will be skipped
  3. folders or files that begin with bash will be skipped
  4. you may specify additional directories to be skipped via the sSkippedBashInstallersDirs ini setting

Now BAIN will try to classify the packages it detected in Bash Installers into its package formats - if it fails the package will display as unrecognized and will have to be restructured.

BAIN-Compatible installer layout Back to top

When scanning an installer (package or project) BAIN follows some rules to decide what's in there and if it can be installed. BAIN will search for specific directories and file extensions (bsa/ba2, ini, all plugin extensions). All directory detection is case insensitive. Directories BAIN is aware of, independent of the game, are:

Wrye Bash Directory Notes
bashtags Its contents will be copied into Data/BashTags.
bash patches BAIN will install files in this folder from packages, usually in the form of .csv files.
docs Its contents will be copied into Data/Docs.
ini tweaks INI tweaks inside this will be installed in Data/INI Tweaks and appear on the INI Tab - do not include subfolders in ini tweaks.
screenshots Its contents will be copied into Data/Docs.
screens Its contents will be copied into Data/Docs.
ss Its contents will be copied into Data/Docs.
Game Directories Supported For All Games
ini, meshes, music, sound, textures, video

There are also game-specific directories:

Game Extra Game Directories
Morrowind animation, bookart, distantland, fonts, icons, mwse, shaders, splash
Oblivion _tejon, config, distantlod, enhanced economy, facegen, fonts, knights - revelation music, menus, obse, pluggy, scripts, shaders, streamline, trees
Fallout 3 config, distantlod, facegen, fonts, fose, menus, uio, scripts, shaders, trees
Fallout: New Vegas config, distantlod, facegen, fonts, menus, nvse, uio, scripts, shaders, trees
Skyrim asi, autobody, calientetools, dialogueviews, dragonbornvoiceover, dyndolod, flm, grass, interface, kreate, lodsettings, mapmarkers, mapweathers, mcm, mlq, nemesis_engine, netscriptframework, osa, platform, scripts, seasons, seq, shaders, shadersfx, skse, skyproc patchers, slanims, strings, tools
Fallout 4 dtf, dyndolod, f4se, folip, interface, lodsettings, materials, mcm, misc, programs, scripts, seq, shadersfx, strings, tools, vis
All these directories (either in the Global or Extra and Bonus Game directories) constitute the standard game directories for this game. If Has Extra Directories is not on for the package, any other top level directory in the (sub)package will be skipped (and their content listed in Skipped tab). There are also some directories and files that will be always skipped (for all the gory details see Skipped Files).

There are, loosely speaking, four types of BAIN-compatible package structures:

Structure Description
Simple The package has .esp, .esm, .esl and/or .bsa files, and/or any of the standard game subdirectories at the root level.
Complex The package has top-level subdirectories that each have a simple structure (as defined above). The top level subdirectories (known as sub-packages) must NOT have the same name as any of the standard game directories for this game (like docs, or meshes). Otherwise BAIN will think that this is a simple package and will treat it as such.
Each top-level subdirectory will be treated as a sub-package, and can be independently activated or deactivated as desired.
Complex/Simple A complex package with only one top-level subdirectory. It is treated as a simple package, starting at this top-level subdirectory. Examples include mods packaged with a top-level Data directory.
Scattered A package with no recognizable structure, that can nonetheless be handled by BAIN because it contains information that lets BAIN make sense of the scattered files in the package. The only currently supported type of scattered package is an FOMOD-guided scattered package, shown as Scattered (FOMOD) on the Installers tab.

Note for mod authors: it is strongly recommended that you use either a simple or complex structure, not a scattered one! This will make it easier for users to inspect your package and will even allow them to perform the installation by manually checking the sub-packages. All major mod managers support these types of packages.

Restructuring Packages to be BAIN-Compatible Back to top

The easiest way to tell if a package needs manual converting to be compatible with BAIN is to try installing it. If it is listed in the Package list with a grey checkbox and name, then BAIN cannot install it. Due to BAIN's flexibility, many mods are already packaged in ways that are compatible, but for those that are not, there are a few possible cases:

If an archive has a BCF, it can be converted for installation with BAIN using the following instructions.

  1. Ensure that the BCF is installed in the correct location, [Game] Mods\Bash Installers\Bain Converters. Also ensure that the archive(s) it converts is/are in [Game] Mods\Bash Installers.
  2. From the BAIN installers list, select the archive(s) to be converted (i.e., the source packages) and right click on the selected file(s) to bring up the context menu, and select Conversions to open the sub-menu.
  3. Click on Apply to open a second sub-menu and select the BCF from it. There may be more than one BCF listed if multiple installed BCFs can convert the selected package(s). An asterisk ('*') is added to the end of a BCF's name for every archive it converts that isn't selected.
  4. Optionally choose a name for the converted archive(s).
  5. Once Wrye Bash has finished the conversion, the converted archive(s) will appear in the BAIN package list ready for install. You can now delete the original archive(s).

If a package is unrecognised by BAIN and has no associated BCF, its contents will have to be rearranged so that the structure matches one of the three types of BAIN-compatible package structures.

Installing/Uninstalling Via BAIN Back to top

Packages must first be placed in the [Game] Mods\Bash Installers directory. This can either be done via Windows Explorer, or by dragging and dropping the package into the Wrye Bash window when the Installers tab is open. If you drag and drop, you will be asked whether you want to copy the package or move it.

For the most part, you can simply right-click the package and select Install..., which will automatically use wizards and FOMODs if they are present, and fall back to manual configuration if they are not. If you want to learn more about each type of package and how to install and configure their options manually, read on.

If a package contains a BAIN wizard (i.e. there is a magic wand icon overlaid on its checkbox):

  1. Right-click the package and select Install.... Alternatively, select Advanced Installation.. > Wizard Installer.. > Manual Wizard.... You can also choose to install using the Wizard's default options by selecting Auto Wizard....
  2. Navigate through the steps of the wizard to install the package. If you picked Auto Wizard..., you will instead be skipped to the wizard finish screen.
  3. At the wizard's finish screen, click the Finish button to apply its selections.

If a package has an FOMOD wizard (i.e. there is an FOMOD radio button):

  1. Right-click the package and select Install.... Alternatively, select Advanced Installation.. > FOMOD Installer.. > Run FOMOD.... Note that Install... will prefer BAIN wizards over FOMOD wizards, so you may have to use this alternative method from time to time, e.g. if a BAIN wizard turns out not to work.
  2. Navigate through the steps and choose options.
  3. At the wizard's finish screen, click the Finish button to apply its selections.

If a package has a Simple or a Complex/Simple structure:

  1. Select the package in the package list.
  2. Choose which plugins to install from it using the Plugin Filter box to the far right of the package list. Checked plugins will be installed, while unchecked plugins will be skipped.
  3. Right-click the package and select Install....

If a package has a Complex structure:

  1. Select the package in the package list.
  2. Choose which sub-packages to install from the Sub-Package box to the right of the package list. Checked sub-packages will be installed, while unchecked sub-packages will be skipped.
  3. Choose which plugins to install from it using the Plugin Filter box to the far right of the package list. Checked plugins will be installed, while unchecked plugins will be skipped.
  4. Right-click the package and select Install....

If a package has a Scattered structure, you must use a guided installation type (see the instructions for FOMOD installation above).

If you install a package then later change the sub-packages or plugin files selected, you can apply these changed by right-clicking the package in the list and selecting Anneal. A Wizard provides a scripted installation method that can be useful for more complicated mods with many options.

When a package is installed, BAIN installs any files that appear to be documentation into the Data\Docs folder. Any files that are simply named readme (e.g. readme.txt, readme.html, readme.doc) will be renamed according to the package name to prevent packages overwriting each other's readmes.

To uninstall any package from the Installers tab select the package and right click on it, then select Uninstall. This will uninstall all Matched files. However, BAIN will not uninstall mismatched files.

A mismatched file is a file that has been altered after it was installed. The reason BAIN does not uninstall mismatched files is BAIN has no way of tracking the source of the alteration if it was not done through BAIN. For example, if the file was altered because it was replaced by another mod that was installed manually, then uninstallation of the mismatched file may not be desirable. On the other hand, if the file was altered because it was cleaned or edited with TESxEdit, or because it was an ini file that was edited with a text editor, then it may be desired to uninstall the mismatched file along with the package that it came from.

Such files could be deleted from the data folder manually, but there is an easy way to do this through BAIN. Before uninstalling the mod, first select the package and right click on it, then select Advanced Installation > Install Configured. This will overwrite any mismatched files with the version of the file contained in the package, making them Matched. Now select Uninstall and BAIN will uninstall all installed files associated with this package.

An alternative, if you want to keep the mismatched file in the to-be-uninstalled package, is to use Sync From Data....

You can also uninstall packages that BAIN hasn't installed, which will remove any installed files that match the ones in the package. This is useful for cleaning out mods that were manually installed. Of course you need to add the packages to BAIN first. Uninstalling via BAIN respects the ownership of files, i.e. uninstalling a mod that contains files also installed by a mod listed lower in the installation order will not uninstall the lower mod's files. See the next section, BAIN Package Order for more on this. However, if the Auto-Anneal option is enabled (the default), then files from other packages previously overridden by the uninstalled package's files will be automatically restored.

BAIN Package Order Back to top

The Install Order of packages in BAIN is important as this decides which package gets its files installed in the case of resource conflicts.Packages may be listed in Install Order by left-clicking on the Order column header. If two packages try to install the same file, then the package installing later in the list will have its file overwrite the file of the package installing earlier in the list. For example, files in a package in install order position 06, would overwrite conflicting files in a package at install order position 04. Note that packages with a higher install order appear lower in the list of packages, and that may lead to confusion as people refer to them as "lower".

The order of sub-packages within a package follow the same rules as packages. Checked sub-packages later (lower) in the sub-package list will overwrite conflicting content from sub-packages earlier (higher in the list) than them.

Package conflicts are detailed in the Conflicts tab to the right of the package list when you select a package. This tab tells you which packages have which files that conflict with files in your currently-selected package. It gives this information for packages in the Install Order both earlier and later than the selected package in the package list.

BAIN allows you to easily adjust the conflict status of packages by moving their order around. This can be done by dragging and dropping packages within the list, or by right-clicking packages and selecting the Move To... option. You can also select multiple packages and move them, in which case they will be moved as a group, retaining their order relative to one another in their new location. A third option is to select the package(s) and use Ctrl+Up Arrow (↑) or Ctrl+Down Arrow (↓) to move them up or down, respectively.

What Symbols & Colours Mean Back to top

BAIN uses the colours of packages in the package list and the state of their checkboxes to convey information about their status to the user. A checkbox state may be combined with any checkbox or text colour, and the possible states and colours are described in the tables below.

Note: Installed packages are marked with a plus, e.g. Green Plus. Corrupt or incomplete packages are marked with a cross, e.g. Red X. Packages that begin and end with ==, e.g. ==Last==, are marker packages. They don't represent an archive or folder and so contain no files, but may be used to organise the package list.

Checkbox ShapeMeaning
diamondThe package is a Project, i.e. a directory rather than an archive.
squareThe package is an archive.
Checkbox Color Meaning
green All the files in the package are installed as configured.
red Some or all of the files in the package are not installed as configured.
orange All the package files are installed, but the plugins are not identical (e.g. one package installed mymod.esp, another package installed a cleaned version of that plugin).
yellow All the package files are installed, but some resource files (i.e. anything but plugins) are not identical (e.g. one package installed textures/mytexture.dds, another package installed a higher-resolution version of that texture).
white The package, as configured, has no files to install. This can happen for complex packages where none of the sub-packages are selected for installation. Will also happen for scattered packages that need to have their guided installation run.
grey BAIN does not recognise the structure of this package and so cannot install it.
no checkbox, just a red X The package is corrupt or can not be read by BAIN for some reason.
Text FormattingMeaning
Navy BlueThe package contains sub-packages.
GreyBAIN does not recognise the structure of this package so cannot install it.
Orange BackgroundThe install is dirty. This will occur for packages for which the configuration has been altered (either by altering active sub-packages and esmps, or by altering the package itself). This can be repaired by running Anneal or Anneal All.
Yellow BackgroundThe package has "underrides" i.e. some of its installed files should be overridden by higher order packages. This may happen after reordering mods that have already been installed. It can be repaired by running Anneal or Anneal All.
Grey BackgroundSome files present in the package will not be installed. This can be due to having a complicated structure only partially handled by BAIN, or having file types that BAIN skips. This can sometimes be fixed by telling BAIN that the package has extra directories by selecting in the right-click menu.

Useful Context Menu Commands Back to top

The following commands found in the package and column header context (i.e. right-click) menus are often useful for many users.

Column Header Context Menu
Command Description
Files.. Open Folder... Open the Bash Installers directory in your system's default file explorer. You can press Ctrl+O to the same effect.
New Marker... Create a marker for organising your packages. The == will be added for you. You can press Ctrl+Shift+N to the same effect.
Data.. Clean Data... Remove content that isn't from the vanilla game or installed via BAIN from the Data folder. The files are not deleted, but moved to the [Game] Mods/Bash Installers/Bash folder instead.
Refresh Data Re-scan the Data directory and all project directories. This is done once per run of Wrye Bash, when the Installers tab is first opened. If you manually alter the directories after that, you should run this command to update BAIN to reflect the changes. BAIN refreshes itself automatically if changes are made to packages in the Bash Installers directory.
Packages.. Anneal All Install any missing files for active packages and correct all install order errors.
Uninstall All Packages Uninstall all packages.
List Packages... Display a list of projects and archives and copy the list to your clipboard. This is useful for posting your package order on forums, e.g. when troubleshooting an install.
Package Context Menu
Command Description
File.. Open... Open the selected packages in the file system. You can double-click a package or press Enter to the same effect.
Rename... Rename the selected packages or markers. You can click on an already selected item or press F2 to the same effect.
Duplicate... Create a copy of the selected packages.
Delete Delete the selected packages and/or markers. Deleted packages are sent to the Recycling Bin, not permanently deleted.
Open At.. Attempt to open the selected package's page on the selected site. If Google is selected, performs a Google search for the package name. For the other two sites, this command assumes that the trailing digits in a package's name is the package ID at the sites. If this assumption is wrong, a random page, or an error page, will be opened.
Open Readme Open the package's readme, if BAIN managed to find one in it.
Anneal Install missing files and correct install order errors according to the package configuration.
Quick Refresh Refresh all info for the selected package(s). Useful if BAIN's information about a package has gone out of sync with the Data folder, e.g. because you manually changed something in it.
Move To... Move the selected packages to the specified position.
Sync From Data... Copy files from the Data folder into this package that are also in the package, but whose contents differ. Useful if you altered a file from this package, e.g. by cleaning it in xEdit, and now want to update the package contents to match.
Install... Install the selected packages, preferring a visual method if possible.
Uninstall Uninstall the selected packages.
Package.. List Structure... Generate a list of the files and directories in a package and copy it to your clipboard. Useful for posting package structure on forums, e.g. when troubleshooting an install.

Setting Up Load Order Back to top

Wrye Bash's Mods tab.

Overview Back to top

Wrye Bash displays your installed plugins in its Mods tab. Your load order of active installed plugins, which Wrye Bash marks with a ticked checkbox, is important as it decides what plugin 'wins' any conflict between plugins, with later loading plugins overriding those that change the same thing. A mod loading later in the list will have a greater number in the Load Order column, and will "win" if there's a conflict with a mod loading earlier (which will have a lower number). Load order is not the same thing as BAIN install order! Install order determines which package's files overwrite other packages files when they conflict.

Although in general "Load Order" stands for the load order of the active plugins, all installed plugins have a load order assigned to them. In Oblivion, Nehrim: At Fate's Edge, Fallout 3 and Fallout: New Vegas this is based on the modification time of the plugin, in Skyrim and Enderal: Forgotten Stories it is based on a text-file based standard the community agreed on, while Fallout 4 and all later games dump all installed plugins in its plugins.txt, marking active ones with an asterisk (*). Bash needs plugin load order even for inactive plugins to correctly merge inactive mods in the Bashed Patch, for instance.

Plugins may be activated by clicking their checkbox so that it is ticked, or by selecting a plugin or group of plugins and pressing the space bar on your keyboard. Plugins may be deactivated by again clicking their checkbox or pressing the spacebar. If a group of selected plugins contains a mix of active and inactive plugins, pressing the space bar once will activate them all, thereafter it will function as normal.

Some plugins are explicitly dependent on other plugins - they have these plugins as masters. When a plugin is activated, its masters are also activated. Conversely, when a plugin upon which other plugins depend is deactivated, those plugins are also deactivated.

When setting the load order, make sure that Wrye Bash is displaying your plugins sorted by Load Order. Do so by clicking on the Load Order column header near the top of the tab. You can also display the plugins sorted by other attributes by clicking on any of the other column headers. Clicking twice will reverse the display order for any column but Load Order. The load order of plugins is given in hexadecimal digits, from 00 to FE, which is 0 to 254 in decimal. (This number also forms the first two digits of a record's Form ID.)

Note that you can only have a maximum of 255 plugins active at any one time, including your game's master file. Wrye Bash displays a plugin count in its status bar, to the right hand side, in the format Mods: [active]/[installed].

Generally speaking, if you end up with an invalid load order of some kind, Wrye Bash will automatically fix it upon booting or refreshing, but a backup copy (with the .bak extension) will be made before doing so.

ESLs

With the advent of ESL files, the load order system was modified. The following list contains the most important facts you need to know about how Wrye Bash handles ESL files:

  1. .esl files implicitly receive the ESM flag, so they load among masters in the order specified in plugins.txt.
  2. .esl files implicitly recieve the ESL flag, so they are always treated as light plugins.
  3. ESPs with the ESL flag are also treated as light plugins.
  4. ESLs can surpass the 255 mod limit - Wrye Bash allows up to 4096, the theoretical limit, but your game will likely give up long before that number is reached.
  5. The ESL flag is mutually exclusive with the Overlay flag (see below).

Creation Club files (of the form cc*.esl or cc*.esm) are read from the game's .ccc file, if the game has Creation Club support. For example, Skyrim: Special Edition uses [GAME]\Skyrim.ccc, while Fallout 4 uses [GAME]\Fallout4.ccc. Just like the game's masters, this load order is hardcoded, and so it cannot be changed - Wrye Bash will show an error message when an attempt is made.

Overlay Plugins

With Starfield and the advent of Overlay plugins, another addition was made to the load order system. Here are the important facts you need to know about Overlay plugins and Wrye Bash's handling of them:

  1. Overlay plugins do not take up a load order slot at all. This means you can load an unlimited number of them, making them ideal for e.g. conflict resolution patches.
  2. Overlay plugins should not contain new records (i.e. records with FormIDs like XY012345, where XY is greater than or equal to the number of masters the plugin has). If they do, those records will be injected into the first master of the overlay plugin, which could cause all kinds of issues, from spurious overrides to CTDs.
    • Wrye Bash does not let you flag plugins with new records as Overlay plugins and xEdit will not let you save them. The Plugin Checker will also highlight such plugins when run.
  3. Overlay plugins must have at least one master. If they do not, the game will ignore the Overlay flag and treat them as regular plugins.
    • Wrye Bash does not let you flag plugins with no masters as Overlay plugins and xEdit will not let you save them. The Plugin Checker will also highlight such plugins when run.
  4. The Overlay flag is mutually exclusive with the ESL flag (see above). If the game finds both, it will ignore the ESL flag.
    • Wrye Bash and xEdit both do not let you flag plugins with the ESL flag as Overlay plugins and vice versa. The Plugin Checker will also highlight such plugins when run.

Setting The Load Order Back to top

Setting up a correct load order that minimises detrimental conflicts that could cause issues in-game can be a difficult and time-consuming process. Effective load-ordering often requires a knowledge of what each plugin in your load order contains so that you can position the plugins to minimise these conflicts. For simple mods, the description in the mod's readme will usually be sufficient to determine the records it contains, but to be sure a utility such as xEdit is required.

LOOT can be used to greatly simplify the process of setting the load order, as it can correctly position thousands of plugins automatically. However, you may still need to order some plugins manually.

Wrye Bash provides a number of ways for you to set up your load order:

When running Wrye Bash, you can also lock your load order in place to prevent unintended changes to it by selecting the Lock Load Order option in the column header right-click menu. Note that this will prevent other utilities from changing the load order, so uncheck this option if you use such a utility to set your load order. If you use BOSS/LOOT to manage your load order and you also use Lock Load Order, ensure Suspend Lock Load Order is also enabled to allow BOSS/LOOT to function correctly.

Note that for Skyrim and later games Wrye Bash will automatically undo any changes to load order done made by the game's launcher or any utility that does not follow the textfile-based load order standard in order to maintain a fully coherent load order. This effectively means that unintended changes are prevented.

BOSS's Launch Using GUI option.

The Launch Using GUI toggles the use of the command line interface for BOSS with the BOSS GUI. Giving quick and easy access to the additional features the GUI provides such as the Edit User Rules option.

Undo and redo Load Order changes Back to top

Bash features a sophisticated undo/redo load order feature, comprising both load order changes of active or inactive plugins and activating/de-activating plugins. Whether you activate a plugin, drag and drop it in another position, deactivate a plugin (having its children deactivated too) etc, you can always hit Ctrl+Z while the list of mods has focus to undo the operation or Ctrl+Y/Ctrl+Shift+Z to redo it. Bash keeps the load orders (meaning total load order of all installed plugins and active state of the plugins) in its internal structures and will persist those on disc on shutting down, in My Games\<Game>\BashLoadOrders.dat, so you can undo/redo on restarting Bash.

The undo/redo feature will try to preserve as many load orders as possible - so unlike undo/redo in other applications if you have an initial load order state A then change it to B, then hit undo (so you are back on state A), then change it to C Bash will keep in its internal structures the load order states A C B while most other applications would end up with A C. Undo/redo load order state is a relatively new feature (available since 307) so it may have rough edges.

What Symbols & Colours Mean Back to top

Like in the Installers tab, Wrye Bash uses colour-coding and other formatting effects to convey information about the state of plugins. The different types of formatting used and their meanings are explained here. Many of these can be changed in the Color Configuration menu.

Checkbox TypeMeaning
CheckmarkPlugin is active.
PlusPlugin is merged into an active Bashed Patch.
DotPlugin is imported into an active Bashed Patch.
EmptyPlugin is not active, merged or imported.
Checkbox ColoursMeaning
BlueThe plugin's masters are all in exactly the same order as is specified in the plugin.
GreenThe plugin's masters are in the same order as is specified in the plugin, but their precise positions are different (i.e. there are other mods between them). This is not an issue, and can be considered to be just as good as having a blue checkbox.
YellowSome of the plugin's masters are in a different order than what is specified in the plugin. This will be handled automatically by the game, but may hint at an incorrect load order on either your or the mod author's end.
OrangeThis plugin loads before one or more of its masters. This will either cause the game to crash or cause mods to load in unexpected ways and must be corrected.
RedOne or more of the plugin's masters is missing. This will generally cause the game to crash on startup, and must be corrected.
Text FormattingMeaning
Blue Text A master - refer to ESM documentation at the start of this document for more information.
Green Text A mergeable plugin (for games without ESL support) or one that can be ESL-flagged (for games with ESL support).
Orange Text Only for games with Overlay support. An Overlay plugin.
Pink Text Only for games with ESL support. An ESL-flagged plugin.
Purple Text Only for games with ESL support. An ESL-flagged plugin that is also a master. The color is a combination of the blue one for masters and the pink one for ESLs.
Red Text Only for games with Overlay support. An Overlay plugin that is also a master. The color is a combination of the blue one for masters and the orange one for Overlay plugins.
Yellow Text Only for games without ESL support. A plugin that should not be merged (i.e. tagged with NoMerge).
Pink Background Oblivion, Nehrim: At Fate's Edge, Fallout 3 & Fallout: New Vegas only. A plugin that shares its modification date with another plugin. Not a problem unless both plugins are active.
Red Background Oblivion, Nehrim: At Fate's Edge, Fallout 3 & Fallout: New Vegas only. An active plugin that shares its modification date with another active plugin. This must be corrected so that they have different modification dates or else it may break your load order.
Light Orange Background Morrowind only. In Morrowind, plugin files contain DATA subrecords that store the size of the plugin's masters when it was created. If a stored size does not match the one on disk, Wrye Bash will highlight the corresponding master in this color. Also used for plugins that have at least one such size-mismatched master. This is a very low priority warning and can almost certainly be ignored.
Grey Background A ghosted plugin.
Slanted Text A plugin that is recommended to be imported and deactivated (i.e. tagged with Deactivate).
Underlined Text A plugin identified as having dirty edits (Identical to Master, Deleted References, or otherwise necessary cleaning).

Useful Context Menu Commands Back to top

The context menus for the column headers and plugins contain a large number of commands, most of which are unlikely to be of use to the average user so are not detailed here.

Column Header Context Menu
CommandDescription
Files..New Bashed Patch...Creates a new Bashed Patch plugin. Useful if you accidentally delete your current one or wish to have more than one.
List Plugins This lists the load order, including version information, activation status and major load order errors. It can be useful for debugging a broken load order. If the Shift key is held when this command is selected, the CRCs of plugins will also be displayed in the output. If the Ctrl key is held, then the versions of plugins will not be shown in the output.
List Bash TagsThis lists all the Bash Tags applied to the plugins in your load order, and where/how the Bash Tags were specified. It can be useful for debugging a broken load order.
Auto-GhostThe Oblivion game engine has a bug where it reads all the plugins in the Data folder, and this can affect performance when the number of plugins is around 300+. In Skyrim there is a different problem, namely if you have over 508 mod files in your data directory, the engine just plain refuses to load any of them, active or not (see here: Thrashing, thread #1, post #1). Auto-Ghosting adds a .ghost extension to all inactive plugins automatically to prevent the game engine reading them, and so helping to avoid the performance drop. When a ghosted plugin is activated, the .ghost extension is removed, allowing it to function as normal. Note that most other utilities will not recognise ghosted plugins, so there are options available for individual plugins to control which get ghosted. Bash displays a warning if a lot of mods and BSAs are detected that you can disable via the ini.
ESL-Flag Bashed PatchesSkyrim: Special Edition & Fallout 4 only. If enabled, then any built Bashed Patches will automatically be ESL-flagged, saving a load order slot.
Lock Load OrderThis prevents other utilities from altering your load order. More accurately, it detects changes to your load order when Wrye Bash starts or is focused (i.e. on top of all other program windows) and reverses those changes.
Plugin Context Menu
CommandDescription
List Masters...Outputs a list of the selected plugin's masters.
List Bash Tags...Outputs a BBCode-formatted list of all the Bash Tags applied to the selected plugin, and where/how the Bash Tags was specified. It can be useful for debugging a broken load order.
Create LOOT Entry... Creates LOOT masterlist entries based on the tags you have applied to the selected plugin(s). Also tries to figure out the URL that the plugin came from based on the BAIN package it was installed from.
Copy Mod Info...Outputs a report on the selected plugins(s) with the info from the currently displayed columns.
Don't GhostDon't ghost this plugin when it is inactive, even if Auto-Ghost is enabled.
GhostGhost this plugin when it is inactive even if Auto-Ghost is disabled.
Rebuild Patch...Rebuild the selected Bashed Patch using the Python patcher.

Setting Up A Bashed Patch Back to top

Overview Back to top

Wrye Bash's Bashed Patch configuration dialog.

A Bashed Patch is a configurable plugin with three main functions:

  • Merging plugins into itself. Merged plugins can be deactivated, avoiding the 255 plugin limit.
  • Importing specific types of data records from plugins. This can be used to avoid compatibility issues.
  • Applying tweaks to the game. This avoids the need to use other mods to apply the same tweaks.

Bash Configuration Back to top

A Bashed Patch is created by Wrye Bash the first time you run it, with the plugin being called Bashed Patch, 0.esp. It is configured using the plugin context menu command Rebuild Patch.... You should rebuild your Bashed Patch every time you change your load order, before playing the game. The Bashed Patch should be last in your load order, unless you have plugins that explicitly state that they must load last.

The configuration dialog consists of a list of major sections to the left, and the contents of the selected section to the right, with the build and save buttons at the bottom. The sections and their items have checkboxes: checking a section will include all its checked items in the Bashed Patch. Unchecked sections and items will not be included. Some sections don't have any items, and so just need the section checkbox checked.

A short description of each section and some items is displayed near the bottom of the window if the section/item is hovered over. Bolded items are new since the last time the Bashed Patch was built, italicized items will not run because they have no active sources (e.g. no mods to import). Wrye Bash will usually do a good job auto-configuring most sections, but you may want to alter options, especially in the Tweak section.

Bashed Patch Configuration Buttons
ButtonDescription
Build PatchBuilds your Bashed Patch with the current configuration.
Select All (next to section list)Selects all the options/plugins in a section list. If an option has multiple possible values, the first value in the value list will be chosen.
Deselect All (next to section list)Deselects all the options/plugins in a section list.
Select All (at bottom of window)Selects all sections, and all the options/plugins in all sections. If an option has multiple possible values, the first value in the value list will be chosen.
Deselect All (at bottom of window)Deselects all sections and all the options/plugins in all section list.
Revert To DefaultReverts your Bashed Patch to its default configuration.
Revert To SavedRestores the last saved configuration of your Bashed Patch, undoing any changes since you last built it.
ExportSaves your Bashed Patch's configuration into an external file for backup.
ImportRestores your Bashed Patch's configuration from an exported patch configuration.

Merging Plugins Back to top

Plugins that contain only certain types of data records can be merged into the Bashed Patch. This then allows these plugins to be deactivated, freeing up space in your load order.

If you're merging plugins in, you do not need the plugins active to do so. In fact, trying to merge them in Bash will 1 - ask you to deactivate them before hand, and 2 - deactivate them even if you refused that prompt after the Bashed Patch has been created. So if you're merging plugins, leave them inactive before building, then select to merge them in the Bashed Patch build dialog. Don't worry, all the algorithms for the rest of the patchers still work as you'd expect on plugins merged this way.

You should check the checkboxes of all the plugins listed in the Merge Patches section, and ensure the section is checked too.

Do not remove merged mods from your Data folder. They will need to be present when you next rebuild your Bashed Patch.

Importing From Plugins Back to top

Plugins can be tagged with Bash Tags that tell Wrye Bash that they contain certain changes that should be preserved even if another mod also changes the same things. This is usually because the changes are important to the functionality of the mod. Wrye Bash then allows you to choose which plugins should have which types of changes preserved, by selecting from the various Import sections when building a Bashed Patch.

If a section's description in the table below begins with Preserves and two or more mods in its list change the same thing, then the later-loading plugin will override the other plugin(s). Otherwise changes are merged.

Applying Tweaks Back to top

The Bashed Patch lets you independently tweak a large number of game settings. Each tweak has a description that is visible when you select it. Some tweaks have several possible values, with the current value given in [square brackets] in the tweak name. Right-clicking these tweaks will display a menu from which you can select a different value. The tweaks are grouped into different sections:

Section Description When You Should Use It Available For
Tweak Actors Allows you to change a number of the game's settings relating to actors (i.e. NPCs). The decision is entirely based on user preference. All games
Tweak Assorted Contains a set of miscellaneous tweaks to the game. In Oblivion, the Bow Reach Fix and Nvidia Fog Fix are recommended for all users, as they fix bugs that may be uncovered by mods. Also in Oblivion, the DarNified Books option is recommended for users of DarNified UI. In Skyrim and games based on it, the Magic: Summoning Absorption Fix is recommended for all users as it fixes an issue that affects many mods. Beyond that, the decision is entirely based on user preference. All games but Fallout 4
Tweak Clothes Contains a set of tweaks that change settings relating to the game's clothing. The decision is entirely based on user preference. Oblivion & Nehrim: At Fate's Edge
Tweak Names Contains a set of tweaks that change the names of things in the game. Most change the names to change how they are sorted in your inventory. The decision is entirely based on user preference. All games but Fallout 4
Tweak Races Contains a set of tweaks that alter race-related things (e.g. height, eyes, hairs, etc.). The decision is entirely based on user preference. All games but Fallout 4
Tweak Settings Contains a set of tweaks that change various global and non-global game settings. In Oblivion, the UOP Vampire Aging and Face Fix.esp tweak is recommended for all users. Beyond that, the decision is entirely based on user preference. All games

Other Bashed Patch Options Back to top

The Bashed Patch also gives you a number of other sections providing additional functionality besides the above merging, importing and tweaking. These options are described below.

Section Description When You Should Use It Available For
Alias Plugin Names Allows Wrye Bash to recognise some common renamings of plugins that are referenced in .csv data files that it imports as part of some Bashed Patch sections. Renamings should be listed in the text box for this section. The format is Old.esp => New.esp. If you have renamed a plugin that is referenced in a CSV file you have selected in the Bashed Patch's configuration. It is recommended that you refrain from renaming plugins, as it can break parts of Wrye Bash and other utilities. All games
Replace Form IDs Replaces a set of formIDs with another set of formIDs defined by a .csv file. If you use a mod that tells you to use it. Oblivion & Nehrim: At Fate's Edge
Cobl Catalogs Updates Cobl's ingredient and effect catalogs to take into account those added by mods you use. If you use Cobl (a.k.a. Common Oblivion). Oblivion
Cobl Exhaustion Updates greater powers added by the mods that are listed in the selected .csv file options so that they're compatible with Cobl's Exhaustion feature. If you use Cobl's Exhaustion feature. Oblivion
Contents Checker Checks that leveled lists, outfits, recipes and inventories contain the correct types of entries, and removes any incorrect entries. Always. All games but Fallout 4
Leveled Lists Merges changes made to leveled lists by mods to increase compatibility between them. Always. If you don't have any mods that alter leveled lists, the option won't do anything, in which case it doesn't hurt to have it enabled. All games
Morph Factions Updates factions so that they are more likely to work with Wrye Morph. If you use Cobl and Wrye Morph. Oblivion
NPC Checker Assigns hair and eyes to NPCs that are otherwise missing them. Always. Oblivion, Nehrim: At Fate's Edge, Fallout 3 & Fallout: New Vegas
Race Checker Sorts race hairs and eyes. Note that the output of this patcher will appear as an ITM in xEdit. It is not an ITM. Do not clean it. The xEdit team cannot fix this problem because of the number of mods that would show as conflicts if it were fixed. See this discussion with ElminsterAU, xEdit's developer, from the xEdit discord. Always. Oblivion, Nehrim: At Fate's Edge, Fallout 3 & Fallout: New Vegas
SEWorld Tests Fixes quests that aren't suspended while your character is in the Shivering Isles. This doesn't apply to mod-added quests, it only restores suspension to vanilla quests where mods have removed it. Always. If you don't have Shivering Isles, the option won't do anything, in which case it doesn't hurt to have it enabled. Oblivion
Timescale Checker Adjusts the wave period of grasses to match changes in the timescale. Note that this patcher is incompatible with plugins that change grass wave periods to match a different timescale. Uninstall such plugins before using it, as their functionality will otherwise be duplicated by this patcher. Always. Does nothing if you are not using a nonstandard timescale, in which case it doesn't hurt to have it enabled. All games

Applying Ini File Edits Back to top

Overview Back to top

Wrye Bash's INI Edits tab, editing SkyrimPrefs.ini, Oblivion.ini, and All Natural.ini, a mod's configuration file.

The INI Edits tab allows the user to quickly apply edits to the games's INI file (e.g. Oblivion.ini, Skyrim.ini, Fallout4Custom.ini, etc.) depending on your game, and mod-added ini files, including those containing scripts used to configure mods. Edits are applied from ini tweak files, which are just a text file that contains only the lines of the ini that you wish to change. Ini tweaks are stored in the Data\INI Tweaks folder, and may be installed through BAIN or placed there manually.

The drop-down box allows you to select the current ini file. The Browse... option in the drop-down box can be used to select an ini file not listed.

Selecting a tweak will display its contents in the middle column, and highlights the changes it applies to the current ini file in the right column. To apply a tweak, right click it and select Apply.

Supported file types are .cfg, .ini and .toml. Note that only "INI-like" TOML files are currently supported. That means some arrays and nested tables won't be correctly parsed. See the TOML spec for more information on this terminology.

Warning: Incorrect INI settings in the game INI can cause bugs, CTDs or other damage to your game. Advanced settings in particular tend to be machine-specific and should not be casually copied from one computer to another.

Launching Applications Back to top

Wrye Bash's launcher bar, at the bottom of its main window.

At the bottom left of Bash's main window you'll find launch buttons for your game and other applications if they're installed. You'll also find a few toggle buttons and some Wrye Bash feature buttons. Each of the application buttons will be present if the corresponding application is present in the game install directory, or in their default install location if the application is not game-specific.

Clicking an application's icon will launch it, and clicking a toggle button will change the state of the toggle. Clicking a Wrye Bash feature button will open that feature's window.

Toggle Buttons Back to top

Be careful not to use up all the available space and prevent tooltip messages appearing next to the Launcher Bar

Troubleshooting Back to top

Generating A Bug Dump Back to top

Wrye Bash writes debug information and error reports into a BashBugDump.log file next to the Wrye Bash.exe file (or next to the Wrye Bash Launcher.pyw file if using the Python version).

That log file will detail the cause of the problem that is stopping Wrye Bash from starting. Read it and the rest of this section to see if the problem is something you can fix yourself. If not, report it to an official Wrye Bash thread for support.

File Permissions Back to top

If you are running Windows Vista or later, Wrye Bash (and other modding programs) may be prevented from working correctly by the UAC security feature. For Windows Store games, there are no workarounds to this, if you receive errors you must launch as as Administrator (workaround 4). There are four common workarounds to this problem:

  1. Install the game outside Program Files or Program Files (x86). UAC prevents unauthorised edits to these folders, so by installing the game outside of them, you remove it from UAC's reach, allowing you to use mods more easily. Steam users can move their Steam installation and games using these instructions.
  2. Deactivate UAC. This can be done from the Control Panel, and will turn UAC off across the whole of your computer. It is up to you whether you feel that you have adequate security measures in place to do this without risk.
  3. Give yourself Full Control permissions over your game install folder. This will allow you to make any edits you desire while keeping UAC active and on guard for any edits made by programs you do not run, and also means that you do not need to reinstall your game to a new location.
  4. Do nothing. Wrye Bash will detect if it needs to run as Administrator, and give you a dialog with a few options:
    1. Start Wrye Bash as Administrator: This will give Wrye Bash full Administrator Rights, allowing it to function fully with no further action, with one exception:
      • You will not be able to drag and drop archives into the Installers window to move or copy those archives into BAIN. This is because non-Admin processes (explorer.exe) are not allowed to communicate with Admin processes (Wrye Bash) in this manner.
    2. Start normally. This will start Wrye Bash without Administrator Rights.
      • Many actions that require Administrator Privileges will cause a UAC prompt to be shown. Commonly, these are:
        • The first time Wrye Bash is started, approximately 4-6 times, depending on the number of directories Wrye Bash needs to create.
        • When the Bashed Patch is rebuilt, 2 times, once for the Bashed Patch itself, once for the associated readme.
        • Installing, Uninstalling, Annealing, and other operations in the Installers Tab that require modification of the game's Data folder.
        • On shutdown, you may be prompted multiple times when saving various .dat files to the Bash Installers and Bash Mod Data folders, if these folders are under UAC protection.
      • A few actions are restricted:
        • Saving files into the UAC protected area: Windows does not allow the Save File dialog to select a target within a UAC protected folder.
        • Ghosting: Wrye Bash will not be able to un-ghost already ghosted mods. Wrye Bash will not ghost mods. Both of these require renaming mod files.
        • Other actions that require Administrator Privileges may not have workarounds coded. Be warned, any errors you encounter while running as a non-Admin under a UAC protected directory will most likely not be fixed. Follow one of the alternate solutions to solve these errors.
    Launching Wrye Bash with some command line switches can avoid this dialog:
    • --no-uac: Always start normally, without Administrator Privileges
    • --uac: Always start as Administrator (if required)

For those that wish to take the third option and give themselves Full Control permissions, here is a guide:

  1. Right-click the folder you wish to change the permissions for, and select Properties.
  2. In Properties, select the Security tab, and click the Edit... button. A UAC prompt may appear, simply allow yourself to continue.
  3. In the Group or user names box, select the Users option.
  4. In the lower box, check the box opposite Full Control in the Allow column. Press OK to exit. If a UAC prompt appears, allow the change.
  5. In the Properties window, select OK to exit. You should now have Full Control permissions over your chosen folder.

If your game is a Windows Store game (Installed via the Windows Store or Xbox App), then there are additional permissions to deal with:

  1. Wrye Bash will by default use a different writable location to store your installers, as well as metadata about those installers: Your My Documents\Wrye Bash folder.
  2. Wrye Bash may need to redate plugins and/or BSAs. Unfortunately, we don't currently have a way to do this in non-admin mode, so for these operations you need to either run Wrye Bash as admin, or grant Full Control as described above for the game folder. Specifically, Oblivion requires this on a regular basis to redate plugins for Load Order configuraion. Later games do not usually need this, so they are for the most part safe to run in non-admin mode and without changing file permissions.

Backing Up & Restoring Settings Back to top

The easiest method is to just run the Backup Settings and/or Restore Settings commands, which are available in the Settings menu. These commands do not backup/restore any mod files or saves, just the Wrye Bash settings/data. When run, the commands ask you for the location you wish to back up to or restore from.

If you wish to manually back up your settings, the directories Wrye Bash stores files in are below.

DirectoryContents
[Game]\Mopy Main Bash files. If you're working on any localisation files in Mopy\l10n you may want to back them up.
[Game]\Data\Bash Patches Contains CSV files used by the import/export functions. Back up any CSV files you've exported and want to keep.
[Game]\Data\BashTags Contains text files with Bash Tag overrides. Only needs backing up if you added any custom files (i.e. ones not installed through BAIN).
[Game]\Data\Docs Contains mod readmes. Doesn't need backing up.
[Game]\Data\INI Tweaks Contains ini tweaks. Only needs backing up if you've added custom ini tweaks.
Documents\My Games\[Game] Contains Wrye Bash settings. It is important to back this up.
[Game] Mods (in the same folder as [Game])Contains BAIN packages and other Wrye Bash settings. it is important to back this up.
