Open Mocap
What it is
Open Mocap is a free, MIT-licensed Blender add-on for AI-powered motion capture. It captures full-body motion offline from video and supports hand tracking both offline and in real time. Captured movement can be retargeted to a 3D character rig, with the maker describing the workflow as fully offline and requiring no external software. The add-on is intended for artists, animators, and researchers working with motion capture inside Blender. It runs on Linux, macOS, and Windows, but compatibility is limited to Blender 4.0.0 and earlier. Recommended compatible components include Blender’s bundled Python 3.10, MediaPipe 0.10.14, OpenCV-Python 4.11.0.86, and CVZone 1.6.1. The maker cautions that newer versions of these dependencies may cause runtime errors. The project welcomes bug reports, performance improvements, feature and documentation contributions, and pull requests. Help is available by emailing [email protected] or opening a GitHub issue.
