Hi everyone,I am a new developer for xcode.I was download the capturing body motion sample code.https://developer.apple.com/documentation/arkit/capturing_body_motion_in_3dWhen I using build a 3d model and replace the default model (robot.usdz), Some part of joint would become bending or become incorrect location.for example:The leg are normal to move and control, but the spine would rotation 90 degrees to backward.However, When I chcek the model with "blender", the model is correct. Have anything I need to edit or add on the sample code (such as viewcontroller)?
