Delirium

Delirium lives in close-up. The film leans on exaggerated expressions and fast changes of mood, so the facial rig was built for range first and subtlety second, then dialed back where the animators needed finer control.

The rig uses joint-based controls for the big shapes (jaw, brows, cheeks) with helper joints driving secondary motion, and a layer of blendshapes on top for the shapes joints can't reach. Correctives fix the combinations that break, like a wide open jaw with a full smile.

Notes came in through dailies and ShotGrid; several shapes were reworked after the first expression tests with the animation team.
