About this mod Machine translation

When you close the Mod Manager or launch the game through the Mod Manager, it sets the plugings.txt and

DLCList.txt is readonly.

I'm not 100% sure, but I believe the Fallout 4 Launcher resets them and inserts all esp files into the data folder.

Mod Manager will create a "Mods" folder in Fallout4/Data to manage installed and activated mods.

Don't delete it.

Install Mods

After clicking install, you can browse zip, rar or 7z files.

This will open a Mod Solver dialog similar to the one in Mod Organizer when a mod cannot be automatically processed.

As of 1.0.21, Mods are installed in the cache folder in Fallout4/Data/Mods/Cache.

Mod solver

Just select the files there (drag and drop) so that the files are structured correctly and installed.

Correct structure means that the base node in the tree view represents the data folder.

Esp files and folders (such as textures, meshes, audio, etc.) need to be children of this node.

Basically make every drag and drop into the data folder a child of the data node.

Uninstall Mods

When uninstalling a mod, Mod Manager deletes all files for the mod and attempts to clean the data folder.

What this does is basically go through all the folders and delete the ones that don't have files.

Activate/deactivate Mods

As of 1.0.21 Mods are no longer installed directly into the data folder.

Instead, you must activate them to use them.

question

  • My game crashes on startup after using mod manager

The solution to this seems to be to delete Fallout4.ini and Fallout4Prefs.ini

%USERPROFILE%/ documents / my games / fallout4

Let Fallout 4 Launcher recreate them.

But please also make sure that plugins.txt and DLCList.txt

%LOCALAPPDATA%\ Fallout4

No longer read-only

The reason is unclear.

Requires .Net 4.5

Install & use Install: follow the bundled instructions

  1. Unzip the archive from playbuff and read the bundled readme / instructions first.
  2. There is no universal mod manager for this game: some mods replace game files directly, some go into a game-specific Mods folder, and some need a game-specific community loader or tool first — follow the bundled readme.
  3. Place the files exactly as the readme says; mods with listed dependencies need those installed too.
  4. Launch the game to confirm it loaded; some games require enabling mods in settings or an in-game mod menu.

Install locations vary a lot between games and mods — the bundled readme is the most reliable guide.
