Effective way of using spine animation as sprite

Hi, in my game I used alot of spine animation. I don’t want to create separate for that spine to save memory usage. But the render overhead is quite high compare to sprite even when I set timeScale = 0 and cache to SHARE_CACHE. So how can I optimize this? Thanks in advance.

SHARED_CACHE should be the best way, especially when you play the animation multiple times.
