Okay, I have video to explain this, but I will attempt to explain. I edited the file "tg03pestpoison.nif" - it's located in skyrim\data\clutter\potions... What is happening: the potion I created floats on the stopper, and won't stop (in game). I can explain the steps I went through to add an object. Anyway, the result I get using this .nif is always the same. Whatever I try to do with it, it floats and wobbles in game. It does fall, but I'm wondering how to fix this. I'm somewhat aware of how Statics are associated with it, but I'm not sure how to start learning Skyrim physics... Also, I have another mesh which I created by deleting out everything (that I could see) from the data\furniture\alchemyworkstation.nif - just wanted the simple mortar. It doesn't move at all, just sort of hangs there in space. How do I give that the same physics as say, a wooden bowl, a misc. clutter item? or sheers? a misc. moveable? I would really appreciate some help, thanks for your replies. -Ether
