What was the hack you "added"? and what do you mean by two model hacks?
1 hack is for the Beam Sword and another for the Homerun bat. They are both Model hacks and they both use textures that go by the same name. Because they go by the same name (or node or whatever) I'm assuming that's the problem, so now the new question is, how do I change it with the Textures still working if that's even possible.
