        I am looking into this example of capturing body motion in 3D:

        https://developer.apple.com/documentation/arkit/capturing_body_motion_in_3d

         

        The example given is using hi-fidelity skeletons hierarchy as USDZ. So I give it a look at the skeleton inside XCode, and trying to replicate the skeleton hierarchy hoping that my MUCH SIMPLER 3D character skeleton will just work. I have maybe just 20-30% of all the skeletons. I omit some nodes.

         

        But my character does not work, it seems to give error like could not find skeleton X.

         

        2019-07-15 22:36:43.985210+1000 BodyDetection[4434:181726] [API] Created entity character does not contain supplied joint name: spine_4_joint.

        2019-07-15 22:36:43.985257+1000 BodyDetection[4434:181726] [API] Cannot get joint count for non-character entity.

        Error: Unable to load model: The operation couldn’t be completed. (RealityKit.Entity.LoadError error 4.)

         

        Is it actually possible to supply a USDZ character with less skeleton, or mayb just from chest and above, or maybe even just left hand and right hand?

         

        Thanks!
