An animation layer available for keyframe animation.

Infinite animation layers that can be targeted at some objects and bones (5 stars are important, especially for game animators)

• Layers can collapsing
• Add only necessary frames when collapsing.
• Editable motion tracks to interact with the current operating layer
• For the calculation of rotation, you may need more optimization,maybe or can only apply the curve handle automatically for convenience (such as quaternion calculation, and then press Euler to return to the key frame, apply the automatic handle)
