1.) Use full body tracking (7 point used in this example: chest, hip, Lfoot, Rfoot)

2.) Set "FBT Locomotion Animations" to off.

3.) Set "FBT Spine Mode" to "Lock Head"

4.) Move around with the joystick.

5.) Notice your avatar and hands do not shift around as you start and stop movement, this is expected behavior.

5.) Change FBT Spine Mode to "Lock Hips"

6.) Move around with joystick again.

Observed Behavior: The entire avatar shifts whenever you start and stop moving, including your hands, head, and hips.

Expected Behavior: Tracking should feel just as smooth as Lock Head mode when you start and stop moving.
