Emotion Cap is a facial motion capture add-on that enables real-time face animation in Blender using a standard webcam. It tracks facial expressions and maps them to 3D characters utilizing the 52 standard ARKit facial blendshapes, ensuring compatibility with modern character rigs, including those from Character Creator 4 (CC4). The tool requires no specialized hardware, allowing animators and creators to preview and record live facial performances directly onto their custom rigs.
