Well when I try to put my .NIF file into the game. It says it can't be loaded and gives me the nice error.nif picture. The awesome < ! >. I've been going though a long process of converting from .3ds with blender to .nif with NifSkope. Pretty much I'm trying to start a raw model from scratch.

You need to provide some more info otherwise it's a guess.

My guess? Morrowind needs 4.0.0.2 Nifs. You may have produced a different version, as there are many and Nifskope supports them.

Alright. I did some research on 4.0.0.2 and now I've got my files working!!! The problem I had was the wrong programs and such. Nifskope didn't help me out too much. The Blend_Nif_script is what I used. Thanks for the help for telling me about 4.0.0.2!
