Currently, VRC Animator Tracking Control switches between IK and animation instantly in a single frame as soon as the state behavior is entered, making smooth transitions impossible.

This sudden, drastic movement often affects PhysBones attached to Humanoid bones, causing them to clip through PhysBone colliders and get flipped inside out.

Another issue occurs in desktop mode: when disabling Auto Footsteps and wanting the avatar's lower body to snap back to facing forward while stationary after moving, this can be achieved by switching the tracking type from Animation to Tracking. However, because Animator Tracking Control lacks a blend time, the orientation snaps instantly in a single frame, looking very unnatural.

Additional Request:

Please add boolean parameters (built-in avatar parameters) that allow us to read the current tracking state of each body part.
