ComfyUI-MAMMA is a new set of custom nodes that brings markerless multi-camera motion capture into the ComfyUI interface. It allows users to process synchronized video to fit 3D body models directly within their existing workflow. The tool takes video inputs and runs a full capture pipeline to produce usable 3D animation files.

The project was created by rethink-studios to integrate the MAMMA motion capture system into a more accessible node-based environment. They built a self-contained Python installer that sets up the necessary environment without altering your existing ComfyUI setup. This development effort makes complex markerless capture technology easier to manage for users with supported hardware.

Motion capture features and target users

Key Features

Processes synchronized video for body fitting.
Exports animated USD files for software.
Includes preset orientations for Maya and Houdini.
Runs in a self-contained Python environment.
Contains an example workflow for quick setup.

This tool is built for 3D artists and animators who need to capture human movement without using physical tracking suits. They can benefit from the direct export to standard visual effects software like Blender or Unreal Engine. Anyone working with multi-camera video setups will find the automated pipeline helpful for creating production-ready geometry.

Installation requirements and project notes

Users should be aware that this is not a simple plug-and-play download and requires a fairly involved setup process. You must register for two separate free accounts to download the required gated model weights, which takes about 20 to 40 minutes on Windows. Currently, the automated installer only supports Windows with an NVIDIA GPU, and Linux is not tested.
