FACS taught from mechanics outward
Facial actions are explained through muscles, mechanics, and structure. This inside-out approach encourages artists to learn the underlying conditions of expressions rather than memorizing surface descriptions.

Built for production, not behavioral coding
FACS is treated as a tool for building, evaluating, and debugging facial motion – not as an observational checklist.

Clarifies gaps and edge cases in standard FACS
The course addresses facial movements that are functionally distinct and anatomically relevant, but poorly represented (or missing entirely) in traditional FACS descriptions. These gaps frequently cause confusion in animation, rigging, and facial systems.

Built for reasoning when reference breaks down
Rather than relying on idealized examples alone, this session trains artists to reason from anatomy and structure when facial actions appear ambiguous, blended, or incomplete.

Designed for alignment across teams
A shared mechanical framework reduces subjective disagreements and speeds up communication between animators, riggers, TDs, and researchers.
