Handle tagged as left elbow not being used by any behaviors

[TheOriginalGC]

I'm scratching my head over this one. I'm rigging a new character, and I'm getting the error, "Handle tagged as left elbow (shoulder, wrist) not being used by any behaviors." I have Limb IK added to the puppet layer (for motion library) and I can't figure out what's going on. What's more, body tracking does not appear to be working and I think the two issues are connected.

Can you share screenshots or your puppet?

Things to look out for:

• Check the placement of your behaviors. A behavior will only pick up handles under its layer hierarchy
• Check the view tags. Take out all view tags and see what happens. Do not tag views per layer. They will be treated as separate views, even if tagged the same.

Thank you for your suggestions. It turns out that I neglected to make the Body a subset of the Root layer. It's a wonder it worked at all.
