Installation
Install SwmarlyValheimNetworking.dll and its bundled managed dependencies on the dedicated
server under BepInEx/plugins/SwmarlyValheimNetworking. Vanilla clients can join by default.
Remove SmoothServer, ValheimTune, FiresGhettoNetworking, BetterNetworking, ServerSideMap, and
Serverside Simulations before enabling this package. Those mods patch overlapping Valheim
networking/map methods.
Target build: Valheim 1.0.7 / network version 39 / BepInEx 5.4.2350.
Install & use Install: BepInEx plugin
- The archive from playbuff is the mod itself — usually a BepInEx plugin (a .dll or a plugin folder once unzipped).
- Recommended: use a community mod manager (such as r2modman) — pick this game, import the mod, and the manager sets up BepInEx and its dependencies for you.
- Manual route: install the BepInEx loader in the game folder, then drop the unzipped .dll or plugin folder into BepInEx/plugins/.
- Launch the game — the BepInEx console logs every plugin it loads; seeing this mod in the log means it is installed.
Mods with listed dependencies need those installed too, or they will not load. Options are usually changed in-game or in the plugin's config file. In multiplayer, the host and every client need the same mods installed.
Install these first, or the mod will not work:
