You seem like you'd know the answer to this question, so I'll ask you since CPM tutorials and troubleshooting is so scarce: I have a few non-humanoid Eeveelution models with custom animations. #1 I downloaded from someone else, #2 is a fork of #1 with a different texture, and #3 is a second fork of #1 that's taller with animations I tweaked by hand. #1 and #3, but not #2 have an issue where certain non-armor cosmetic items (eg Cowboy Hat from Biome Makeover mod; Running Shoes from artifacts) will render to an invisible "vanilla" model instead of to the actual model. Bizarrely, #1 and #2 have normal head tracking despite lacking the additive head animation fix, and #2 even has a functional Cowboy Hat despite lacking the fix I had to do for #3 (changing "Head Item"s position). How do I get rid of this invisible Steve that keeps wearing my shoes?
