How do you use BepInEx Configuration Manager in Valheim?

Short answer

Install Official BepInEx ConfigurationManager in the same r2modman or Thunderstore Mod Manager profile as your Valheim mods, then launch the game with Start modded and press F1 in game. The panel only lists plugins that actually loaded and settings they expose through BepInEx Config; it cannot configure a missing or incompatible mod.

The details

In r2modman or Thunderstore Mod Manager, select the Valheim profile you actually play, search for Official BepInEx ConfigurationManager by Azumatt, and install it with dependencies. Keeping it in the profile avoids mixing its files into an unrelated vanilla or test setup.

Start Valheim with the manager's Start modded button, not a normal desktop or Steam shortcut that bypasses the profile. BepInEx must load first; after entering the game, press F1, which is the Configuration Manager's documented default hotkey.

The left side lists loaded plugins or exposed configuration files. Search for a mod name, select it, expand the relevant section, and read each setting description before changing a value. A mod with no BepInEx Config entries has nothing for this panel to show.

If F1 does nothing, first check for a hotkey conflict, then confirm the BepInEx console or log shows ConfigurationManager loading. Verify its DLL is under that profile's BepInEx/plugins tree and that the profile uses a supported BepInEx version; reinstall the package rather than copying random DLLs between profiles.

Whether a value applies immediately is controlled by the mod that owns it. Some mods listen for live changes, while others rebuild data only at world load or process start. Follow that mod's README and restart the world or game whenever its documentation requires it.

In multiplayer, Configuration Manager is only an editor UI; it does not make a client value authoritative or synchronize arbitrary configs. Server-synced or admin-only values may be locked or overwritten. Change authoritative settings on the server as the mod documents, and fall back to the relevant BepInEx/config/*.cfg or other documented config file when no GUI control is available.

Related questions

What should I do if F1 does not open Configuration Manager?
Check that Valheim was launched with Start modded, inspect the BepInEx console or log for the plugin, verify the DLL is in the active profile's BepInEx/plugins folder, and rule out another mod using F1. Also confirm the installed package supports your BepInEx version.
Does every player need Configuration Manager installed?
Not merely to join a server. Each player who wants the F1 editing UI needs it locally, but the gameplay mod's own README decides which clients and servers require that mod. Server-authoritative settings still belong on the server and may be locked for non-admin clients.
