Hello, I’ve made a small tool that takes primitive groups and controller/joint names you want link, and it assigns colors and skin controls values to them. It can also create a mirror group and mirror all controllers to the other side of the body. The geometry can then be used as controls in Apex. Animating like this in apex it’s quite fun and works nicely for a facial rig.
Cheers

For a better visual result we can wash the colors out and apply it over the materials like here.

looks amazing!
