BepInExPack for Valheim

This is BepInEx 5.4.21 pack for Valheim.

BepInEx is a general purpose framework for Unity modding. BepInEx includes tools and libraries to

  • load custom code (hereafter plugins) into the game on launch;
  • patch in-game methods, classes and even entire assemblies without touching original game files;
  • configure plugins and log game to desired outputs like console or file;
  • manage plugin dependencies.

BepInEx is currently one of the most popular modding tools for Unity on GitHub.

This pack's contents

This pack is preconfigured and usable for Valheim modding.
In particular, the changes from base BepInEx releases are:

  • Added preconfigured BepInEx.cfg with console enabled.
  • Added unstripped Unity + Mono BCL DLLs for current versions of the game. See this issue comment for more info.
  • Updated Doorstop configuration and BepInEx to allow to load unstripped DLLs without having to overwrite game DLLs.
  • Added scripts necessary to run both game and dedicated server on Linux machines

Installation (game, automated)

This is the recommended way to install BepInEx on the game.

  1. Download and install Thunderstore Mod Manager or r2modman
  2. Click Install with Mod Manager button on top of the page
  3. Run the game via the mod manager

Installation (server, automated)

There are some managed dedicated server that support simple and automatic BepInEx installation.
Here is a list of known ones (list updated as more is known).

Installation (manual)

If you are installing this manually, do the following

  1. Extract the archive into a folder. Do not extract into the game folder.

  2. Move the contents of BepInExPack_Valheim folder into <Steam Location>\steamapps\common\Valheim.

  3. Check that you have installed it correctly. If done correctly, your folder will look as follows

    BepInEx, winhttp.dll, doorstop_config.ini and unstripped_corlib in Valheim folder.

  4. Follow either Windows or Linux game running instructions below:

Configuration (Windows)

No need to configure. Simply run the game. If everything is correct, you will see a console pop up.

Configuration (Linux, game)

  1. Make executable with chmod u+x

  2. In Steam, go to game's properties and set game's launch arguments to

    ./ %command%

    Note to advanced users: You can change ./ to full path to the script. This way you can install this pack entirely outside of game folder.

  3. Run the game via Steam.

At this moment you will not see any clear indication if BepInEx works. It is suggested to test by installing a simple plugin such as MessageCenter from BepInEx.Utility.

Configuration (Linux, server)

This guide assumes you have enough knowledge working with Linux.
If not, it is suggested you use ValheimPlus instead and server hosts that support it out of the box.

  1. Make executable with chmod u+x
  2. Edit to change the launch parameter like you would with Valheim's own launch script.
  3. Run to start the server.

If done correctly, you will see BepInEx bootstrap messages in the terminal.

Checking BepInEx version and load status

If BepInEx was loaded successfully into the game, you should see BepInEx version info in top left corner of the main menu:
