A demo of a system called Face Cage Rigger.
It's a medium-quality facial rigging system I developed for non-hero digi-double characters. With minimal effort, the facial rig can be completed in just a few hours.
The rigger simply matches the cage geometry to the model, adjusts the skin weights, and that's it.
I extracted the cage shapes from MetaHuman, which provides high-quality FACS shapes. In the demo I applied this system to a cartoony character.
