Faceit is an extension for automating facial rigging and animation processes. It provides a non-destructive workflow where users place landmarks on a character to generate procedural facial expressions adapted to the specific model's topology, whether photorealistic or stylized.

The tool automatically generates the 52 standard ARKit shape keys commonly used for performance capture. It includes utilities for baking deformations from the modifier stack, posing, and sculpting directly into final shape keys. Users can tweak customized expressions using control bones or by sculpting on the registered meshes, with options to mirror poses and sculpt influences. Faceit includes an ARKit Control Rig that interfaces with motion capture utilities and integrates with Nvidia Audio2Face animations via face region filters.
