The setting is correct. I followed the official video tutorial with auto rig hand example. I just found that the tracking result is not stable, sometimes it recognizes my left hand with my right hand, sometimes it recognizes my hands correctly. And the hands are not stable, they are flipped randomly somehow as I am moving my hands. But the tracking result in the hand viewer example is much more stable. I followed the official website to do the rigging, and the result is not ideal. Do you know how to make it stable?
