Spec score 7.4 #27 of 63 in Motion Capture Software

What it is

Open Mocap is a free, open-source Blender add-on for AI-powered motion capture. It captures full-body movement offline from video and tracks hands both offline and in real time. Captured motion can be retargeted to a 3D character rig, with the workflow staying inside Blender and requiring no external software. The maker describes it for artists, animators, and researchers seeking motion capture in Blender. The add-on 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; newer versions may cause runtime errors. The project uses the MIT License and welcomes bug reports, performance improvements, feature work, documentation contributions, and pull requests. Help is available by emailing [email protected] or opening a GitHub issue. There is no facial tracking or API access.
