🎬 Open Mocap — AI-Powered Motion Capture for Blender
Open Mocap is an open-source Blender add-on for AI-powered motion capture. It supports offline full-body pose tracking, offline + real-time hand tracking, and easy retargeting to any rig. Designed for artists, animators, and researchers who want fast, accessible motion capture inside Blender—no external software required.
Open Mocap is compatible only with Blender 4.0.0 and earlier. Newer Blender versions currently do not support the add-on.
Best Compatibilty as of now:
Blender: 4.0.0 or earlier
Python: 3.10 (Blender’s bundled Python — no separate installation required)
MediaPipe: 0.10.14 (Must be installed using the addon)
OpenCV-Python: 4.11.0.86 (Must be installed using the addon)
CVZone: 1.6.1 (Must be installed using the addon)
Developer Note:
To ensure Open Mocap works correctly, install the versions listed above. Using newer versions of MediaPipe, OpenCV, CVZone, or Python may cause runtime errors. However, developers are welcome to experiment with different versions to identify the best compatible setup.⚠️ While installing OpenCV, many times a dummy or incorrect version may be installed. Installing and uninstalling the external libraries listed above was a challenging process during development, and this may be a Blender-specific issue.
