Oblivion/Skyrim-style physics in Morrowind (unofficial OpenMW fork)
Title speaks for itself! Fork of OpenMW 0.52.0 adding object physics, ragdoll, physical projectiles, etc. Can be downloaded here.
Before you ask, yes, this was vibecoded (Opus 5.5), I'm One Of Those People. Frankly, I didn't think this was going to work at all when I started poking at it, but the slop machine greatly exceeded my expectations. Upshot being that I cannot confidently attest to it not being a glitchy mess outside of the opening area. But based on several hours of messing around, it works pretty damn well in Seyda Neen for a proof of concept.
Per my testing, it's compatible with old OpenMW saves, but new saves created in the fork are not backwards compatible due to the way it handles ragdoll information in save files. I haven't tested any OpenMW mods with it yet but in principle there shouldn't be any issues with content mods. Anything that touches physics will probably be a no-go.
