Skeleton animation culling

Hi, is it possible to enalble skeleton animation frustum culling?

I have thousands “walking/runing/idle” entities with AnimationComponent in one scene, they not all are visible through the camera.

I thought that the AnimationComponents would not compute transform when not in camera frustum like render culling, but there is no difference in the calculation time of the two systems TransformProcessor and AnimationProcessor, whether the camera faces empty space or all the thousands of entities.

Am I missing something? Thanks!
