So, I've made a little penguin in blockbench. It replaces the model of a dolphin. But I want the penguin to slide, and not to stand. It's a spawn item in a minigame I'm making, and once you spawn it, it just slides off in the direction you spawned it in. It should slide from the start without an animation.
The problem:
When I rotate it, Minecraft just shows the normal dolphin model. Otherwise, when it's standing, it works perfectly fine.
How do I make it so the penguin is lieing on the floor, and Minecraft still shows the penguin?
(btw it's all in a resource pack, no plugins or mods involved)
