Eyebrow bone is detached from the head mesh Exercising facial expression animation with settlers rig... ...and having a problem with keeping the eyebrow bones on the face surface.
The rig and mesh are from Blender Cloud, Settlers. (see links below)
Transforming the L or R eyebrow controller deforms the mesh freely so it can penetrate the head mesh or depart from it.
My question is how can I attach it to the surface, so transformations are constrained to keep it above and on the head surface?
I tried to lock the y transformation, I added a limit distance constraint (target=head, clamp=surface)- both had no effect.
Any input would be greatly appreciated.

That's easy! All you have to do is add a &quot;Shrinkwrap&quot; constraint to each bone and set the target to the mesh with the head. It'll stick to the surface. One of my favorite modifiers
