Reliable collaboration — live model manipulation and drawing undo

Fixed

  • In physical-tracking modes (image marker, reference object, or active tracker), rotating or scaling the model as the session host now updates for everyone live, as you do it. Previously a rotation only appeared on participants' headsets after you moved the model.
  • Undoing a drawing stroke no longer clears all strokes for the other participants — the strokes that remain stay visible on everyone's canvas.
  • Strokes drawn after an undo continue to sync to collaborators.
