please make it so that the models only show when you rename a mob using nametags or make it a behavior pack like cute mob models except they don't replace vanilla mobs
you can just rename the mob Id from the vanilla behavior to the ones in the resource packs so it behaves as its own entity but doesn't replace the vanilla mobs
(hope this helps❤️)
Your resource packs amaze me, I think I'll add spider girls to my character's story
(hope this helps❤️)
