Greywolf1: The list doesn't mention the Morrowind Code Patch and the Unofficial Morrowind Patch. Is this because their contents are covered by OpenMW? Or because they are considered to be insignificant?
In addition, the list doesn't mention any total conversions like Sword of The Perithia, Arktwend, Myar Arannath, Sea of Destiny, etc. All 4 provide a lot of additional content beyond Morrowind, Tribunal and Bloodmoon. Has anybody tested the compatibility of Open MW with these mods?
Engerek01: I do not know sorry. As I said earlier, I have very little experience with either Morrowind and modding.
I just tried to run Arktwend (the first total conversion of the Nehrim and Enderal guys) under OpenMW, and it does seem to work (at least I could launch the game and take the first few steps). With that said, I still don't see any visual differences between OpenMW Morrowind and native Morrowind (both run at 1680x1050). Perhaps I'll notice a few differences "under the hood" later.
As an aside: The Morrowind copy I'm using for Arktwend has the Unofficial Morrowind Patch (version 1.6.6) activated. I can't confirm that the patch works, but it's likely, as OpenMW runs fine with this esm.
Update: OpenMW is not compatible with Arktwend (at least not for my configuration): There is some occasional screen flickering, and, worse, when you enter the pub after leaving the monastery, your character, together with about half of the pub guests, flies suddenly upwards, through the ceiling to the next floor, but you see through the ceiling and watch the other people in the pub (the game doesn't hang) - and you can't get back down to the ground floor. Looks funny, but is a showstopper.
