layer bone don't stay in place on the scene

Tip #2: Parent a 'leveler' bone with Independent Angle enabled to the character's root bone and then parent the 'mover' bone to this one. This keeps the SBD panel leveled even when you rotate the character.)

I used the panel mover with independent angle, but not the leveler. Great technique, thanks for sharing!

Yeah, I found the Leveler bone is very effective for getting a panel to follow a character, maintain relative distance/position, and for keeping it properly oriented. Also, I can parent multiple panels to the Leveler, and because each panel has its own Mover bone, they can be repositioned individually at any time.

I regularly have at least two panels--body & face controls--but have done this setup with as many as five bone panels. When I get that many panels, I start using adding boxes and notes around each panels to make the grouping and purpose clearer.
