I am working on a project where I am a programmer. I am working with another animator, but I found that two out of the ten animations he sent me consume a significant amount of performance. If there are too many instances in the scene, the frames will drop severely. However, the other animations he gave me do not. But I don't know much about the production of spine animation, and he is only good at creating various powerful animation effects. We don't know much about how spine animation can improve performance. Maybe because he only does animation, he may not care about performance and can freely express himself. I want to know how I can tell him how to make this animation not take up a lot of performance.
