Today I decided to make a quick tutorial about rigging the face. I struggled for a long time trying to make sense of the face, and finally came up with a process that works for me. Hopefully this works for you too!
This rig should work with both high and low poly models, I use the exact same process for either. If you need something more complex, just add more bones to control more areas– this is the idea behind complex face rigs.
Hope this helps someone!
