About Multiplayer

TES3MP is an open source project that adds multiplayer functionality to OpenMW, an open source game engine that supports playing The Elder Scrolls III: Morrowind. The project's repository lists TES3MP version 0.8.1, which is based on OpenMW version 0.47.0. According to the project, version 0.8.1 is fully playable, with synchronization of players, NPCs, the world, and quests, along with state saving and loading.

Server-side Lua scripts can be used to customize these behaviors. The project notes that remaining gameplay problems mostly relate to AI, and that client-side script variables must be placed on a synchronization whitelist to avoid packet spam. A separate VR branch combines the project's code with OpenMW VR. The code is licensed under GPLv3 with additional allowed terms.
