I'm trying to edit an existing mesh in blender (the beggar's cap to be exact). I have Nifskope, I have the nifskript for importing .nif files into blender, but for some reason I keep getting an error message (Value Error: string too long (0x6C0C0000 at 0x0000003A)) in blender when I try to import . I've followed a few different tutorials on editing the BSLightingProperties and user versions or whatever, but non have worked... halp pls
