What Is a Facial Animation Rig?
A facial animation rig is the digital skeleton, muscle, and control system that allows a 3D character's face to be animated. It's a crucial component in games, film, and virtual reality, enabling artists to create expressive performances, from subtle emotional nuances to realistic speech. These rigs can range from simple joint-based systems to complex, blendshape-driven setups used for photorealistic digital humans. They are the foundation upon which animators, motion capture artists, and AI systems build believable and engaging character performances.
