Installation

Requirements

  • BepInEx for Valheim (denikson BepInExPack_Valheim 5.4.2333+)
  • Jötunn (ValheimModding-Jotunn 2.25.0+)

Both are pulled in automatically when you install through a mod manager.

Install with a mod manager (recommended)

  1. Open r2modman or the Thunderstore Mod Manager.
  2. Search for InterServerPortal and install it. BepInEx and Jötunn are added as dependencies automatically.
  3. Launch the game through the mod manager.

Manual install

  1. Install BepInEx and Jötunn.
  2. Extract the InterServerPortal package so that InterServerPortal.dll lands in BepInEx/plugins/InterServerPortal/.
  3. Launch the game.

Where to install it

Setup Install on
Single-player only (portal networks) Your game client
Joining a dedicated server Every player's client
Running a dedicated server The server too (in addition to clients)

On a dedicated server the world-switch logic no-ops (there is no local player on a headless server), so the mod is safe there. Installing it server-side keeps each portal's flag/config/lock networked and persisted with the world, and enables the network lookup for portals in unloaded zones. If you only run listen/host games, client-side is enough.

After installing

  • A per-portal config panel becomes available via L.Shift + Use on any portal_wood or portal_stone.
  • The config file BepInEx/config/com.interserverportal.cfg is written on first launch — see Configuration.

Updating

Because BepInEx loads plugins only at process start, fully quit Valheim to the desktop and relaunch after updating — an in-game "Log Out" (and this mod's world switch) keeps the old assembly loaded.
