Ok so I didn't realize they changed the meshes with FO3, I use NIFskope for Morrowind and Oblivion. I am trying to change the texture of the prewar suit but I do not see the texture spot. (The spot with the little purple flower) How do I change the texture on FO3 Nifs?

It is exacly the same as for oblivion, just develop the lines with the arrows on the right
A picture will be more easy to understand. Here it is : http://imageshack.us/photo/my-images/259/v85f.jpg/
except unlike Oblivion you must put a link to a normal map on the 2nd line.

and the textures must have mipmaps or the geck will display lots of warnings.

That's actually different.

Note where the texture is in Nifskope (On the side not the bottom), thanks for the help though!
