So, I have created a basic model of a Kriss Vector SMG in Blender for my own use but I don't know how to get it in the game. I've tried exporting the file in Blender as a .OBJ and importing in NifSkope but then I just get a whole load of errors and my weapon doesn't appear. Could someone tell me how to actually get from Blender to Fallout 3?
