Character Animator Body Track flickering legs and arms

Hello! I'm testing the Character Animator Body Tracking on the Hopscotch Puppet and I can't get rid of the annoying flickering for the legs or arms. I've tried multiple ways to eliminate the problem, but nothing worked, such as reducing the Tracked Handles to only the head, the wrists and the heels or eliminating the Dragger Behavior. What should I do? Anyone having this issue? I have to mention that I was wearing a light green (lime green) hoodie and my furniture is yellow & orange. Is it possible that the contrast between my hoodie and the environment to be the problem? Any suggestion is greatly appreciated.

An example video would be helpful, but the more noise in the camera signal, the more jitter in the Body tracking output. Lighting does seem like the first thing to check.

    I've found that if overhead lights dip into the camera's view, with face OR body tracking, stuttering or jitter appears. For body tracking, I suggest making sure your entire body from head to toe has good contrast from your surroundings.

     

    At some point, someone will figure out an optimal setup for most everyone, but Dave's tutorials do make it look simple. Maybe there's a notable difference depending on camera quality?

      Limited (2 minutes!!!) experience with Character Animator body tracking, but other packages have generally been sensitive to lighting. So I would suggest making sure the lighting in the area you are shooting is good. I have light panels shining from above and below my camera (and its still not great).

       

      Camera based solutions with AI are very cool and easily adoptable, but not as robust as a real mocap suit or VR controllers.
