Webcam Motion Capture is an AI-powered software that enables users to control 3D avatars using only a standard webcam. It provides real-time tracking of head, facial expressions, hands, fingers, eyes, and upper body. Since its launch in November 2021, it has attracted over 36,700 users from 120 countries. The software supports sending tracking data to external applications via the VMC Protocol, allowing integration with VTuber apps like VSeeFace and game engines such as Unity and Unreal Engine. It can also save motion capture data as FBX files for use in 3D animation software like Blender. The software is available for Windows and Mac, with a free version that includes all tracking features. A subscription is required to hide UI elements or use tracking data in external apps.
