Naturally, as soon as I think something will be relatively simple, it turns out to not be simple at all. xD
I've got some art done for this, I'm just having some trouble getting it to play nicely in the game. It's like it remembers where the texture is supposed to be, and I'm not entirely sure why.
Figuring out what voodoo Soltaire used to get his natural teeth and claws to work correctly is going to come into play too, assuming I can figure out what's going on here to start with. I don't think it's a transparency problem because 1) the entire spine ridge area is not black and 2) other things that need transparency are still working correctly.
