title: Swift Manipulate joint locations of Apples 3d motion cap model
body: <p>I would like to place Apple's 3d motion capture model <a href="https://developer.apple.com/documentation/arkit/content_anchors/capturing_body_motion_in_3d" rel="nofollow noreferrer">robot usdz</a> (found in this code sample) in a view and manually change the position of each joint. In the code sample, a BodyTrackedEntity is used to change the pose of the model based on the pose of a person in the arview, however,  I would like to change the pose of the model by supplying my own transforms. More specifically, I would like to access each joint of the model and assign it its own transform to change the model's pose.</p>
  <p>Any suggestions on accessing and changing the location of each of the models joints manually?</p>
