I found odd behavior in IK-beta.
Test Conditions:
* 6 point tracking
* Force Locomotion animations for 6 point tracking = OFF
* manually set tracking by VRC Animator Tracking Control.
* Set Hip=Animation and Head=Tracking in VRC Animator Tracking Control.
Expected behavior: I can rotate head by HMD movement.
Result(in IK-beta): I can't rotate head by HMD movement.
First half: noHipLocomotion=ON(Hip=Trackiing)
Latter half: noHipLocomotion=OFF(Hip=Animation)
