ComfyUI-MotionCapture

Installation

Three options, in order of speed → reliability:

1. ComfyUI Manager (recommended) — search for MotionCapture in the Manager and click Install from the highest version displayed. If that doesn't work, try nightly.
2. Manager via Git URL — in ComfyUI Manager: "Install via Git URL" with https://github.com/PozzettiAndrea/ComfyUI-MotionCapture.git.
3. Manual (most reliable):

   cd ComfyUI/custom_nodes
   git clone https://github.com/PozzettiAndrea/ComfyUI-MotionCapture.git
   cd ComfyUI-MotionCapture
   pip install -r requirements.txt --upgrade
   python install.py

Please report any problems you hit during installation or use of my nodes — open a Discussion or Issue. Very grateful for your help! 🙏
