I have compiled a list of regressions that I have observed while testing on Vive wands on Live and Avatars3-Beta branch, with both Vive advanced controls disabled and Vive advanced controls enabled.
The regressions boil down to:
  • Vive advanced controls turned ON can no longer perform analog fist gestures
  • Vive advanced controls turned OFF has completely regressed, such as the grip button having a lower priority than the trackpad, fist not triggering automatically when pressing the trigger, gestures not persisting when the thumb is released from the trackpad
  • Thumbs up is missing from the wheel, whereas handopen has appeared on the trackpad
I'm unable to tell which of these changes might have been intentional.
