I'm trying to make a "custom elytra" I got it working all now but the render, I can't even figure out how to render a simple texture on the player (and move with it kinda like a cape), I know how to render custom armor models but that's about it, been looking at the vanilla code, but I can't seem to figure out. If anyone figures out or knows how to do it I'd be grateful if you could share it with me
