Trouble with Auto-Swap while webcam tracking

We have created a character and rigged it to auto swap arms/hands depending on their position. The auto swap arms work fine when we move them using the drag feature. But when we switch to body tracker camera input there are problems. The arms do not move correctly. They will not move in front of the body or down to the character's sides. It is as if the range of motion is limited. Also, the hands move to position but remain stationary if the person in front of the webcam is waving, for example. For additional context, without using auto swap, just a simple single armed character, the camera body tracker works fine.

 

Any help would be greatly appreciated. Thank you in advance.

I will try to confirm this, but auto-swap only works with mouse-dragging input. Not 100% sure, but if so it is very disappointing that we cannot use body tracking and auto-swap together.

It works with the camera, but the tags for the camera (e.g., wrist, etc.) have to be on the same node as the leader tag.

Auto-swap works fine with the body tracker. See Wampler on the home screen as a rigging example.

 

FYI, I spent 5 min re-rigging Wampler to be full-body-trackable and motion-library-compatible. Here is the link if anyone is interested: https://shared-assets.adobe.com/link/091283f5-3dea-41a8-5bc5-9a2c02322e8c

I've used it with both motion tracking and the motion library. It works fine (when you've set it up correctly). My mistake was trying to put wrist and elbow tags on the follower limbs. Big mistake.

How are the follower limbs rigged? There shouldn't be tags on those limbs, just nodes.
