Anime FaceRig is a tool for setting up facial rigs on anime-style characters in Blender. It generates a streamlined rig utilizing three main controllers designed to drive facial expressions, reducing the number of bones required for animation. The add-on works by automatically linking drivers to existing shape keys on your model, and can generate missing shape keys if necessary.

The interface includes operations for importing the rig, attaching it to your model, and linking tweak bones using lattice modifiers for finer deformation control. It also supports custom controllers based on user-created shape keys and includes specific integration features for Hololive MMD and VRoid character models.
