Body Shop Created Clothes Have Weird Lightning Issues

@Cinebar
Well, you didn't clearly say that they don't work with bottoms due to them having bump maps as well, I wouldn't have written a post about it if it wasn't new to me. As I said, I already followed skellington's instructions multiple times and they unfortunately didn't work. :/
Where exactly did you find those default replacement files from that author? I would be interested in checking those out. :)
