Anything I find relating to this issue is for Bedrock, but I'm using Java. Forgive me if this is already covered somewhere and I suck at finding and using key phrases, or I misunderstood other posts because I'm not familiar with some terminology.
I'm trying to make my first model, it's supposed to be a jackalope. I figured I'd start with something I could mostly rip from the base game. I got the model from converting a Minecraft Skin project into a Modded Entity project. Unfortunately it didn't come with the textures or animations of the vanilla rabbit. I was able to remedy the texture issue by using assets from a resourcepack, but that resourcepack also doesn't include animations.
I'd very much not like to try manually matching the animations for my entity to be as indistinguishable from the base entity as possible. I was hoping to avoid having to animate this entity at all, at least until I have some animation and coding experience to give it custom behaviors. Am I out of luck? This seems like a rather inconvenient way of learning how to animate in Blockbench, I think I'd rather make the animations intentionally distinct.
