vandrath: In NifSkope is nothing like "mesh", so I don't know, what to look for. And if you mean "NiTriShape" or "NiTriShapeData", there is nothing like "face normals". I may have bat eyes, but I cant find find anything like this, so, please, exact description. And I still think, that you still really don't understand my problem. I didn't replace the original texture. I used bethesda made model and switched thwo premade models. I just took one model and used it as a replacer for other model. So I think, I just don't need to play with textures, or etc. But I am not sure. So, if anybody would be so kind, try this: make a new item out of any dragonpriest mask. I used the Morokei (moonstone mask). Then, use some 3D modeller (3DSmax, blender, don't care) and replacer the orignal model (dragonhelm_moonstone_1.nif) with worldspace model (dragohelm_moonstone_go.nif) and then save it and make it work in game. This is, what I'm trying to do for at least five or six days with completely no result. Just try it, its work for 30 minutes.
