heres a guess since I dont have it installed but looked at the file contents.
It looks like they might be applied to a geoshell. The paint textures are not build into the actual skin.
If it wont instantly apply to a geoshell then, one image will probably be the base color, another will go under cutout and the third probably is translucency. Just turn the rest of the shell off.
If it works great if not someone with more knowledge of these thing may chime in.
