OpenMW is a free and open-source engine for The Elder Scrolls 3: Morrowind. It aims to be a fully playable (and improved!), open source implementation of the game´s engine and functionality
We are proud to announce the latest version of OpenMW, Version 0.9.0, which was released on 13 January 2011.
New Features
Exterior cells - loading, unloading and management
Character Creation GUI
Character creation
Make cell names case insensitive when doing internal lookups
Music player
NPCs rendering
Known Issues
Sometimes the music track changes whenever you enter a new cell
Exterior rendering is unoptimized (slow) and has no landscape yet
Character creation must be invoked via script instructions, the tutorial sequence at the beginning of the game isn´t fully working yet.
We have a rate crash bug releated to NPC-rendering.
You can pick up things and use load doors (doors that connect cells). Note that the aiming mechanism is only a placeholder. It lacks precision and causes problems in some cases (it will be replaced in the next version).
If you find any bugs/errors with the latest version of OpenMW, please submit a bug report on openmw.com or at the OpenMW forums.
