UPDATE V2 :

NEW: Modular Mesh. several USkeletalMeshe can be attached to one instance now (similar to Leader/Follower pose).

NEW: Dynamic transition. (transitions are generated and cached at runtime when needed, eats less VRAM )

NEW: Dynamic Pose (instances can switch to Dynamic Pose and be bound to a USkeletalMeshComponent, physics simulation and UAnimInstance is possible now)

UPDATE: No more Bone or Influence limit. uint16 bone index and skin weight added, up to 8 influence is supported now.

UPDATE: Animation sequences are generated at load time. AnimCollection takes less disk size now.

UPDATE: AnimCollection uses DerivedDataCache. rebuild won't take minutes anymore.

OPTIMIZATION: only sends render-required-bones to VRAM . SkinWeight is taken from SkeltalMeshes now.

OPTIMIZATION: Spatial Grid for culllig + SIMDified codes .
