Touchdesigner - DMX Lighting - Hand Tracking

Описание: Recently, I’ve been experimenting with using MediaPipe hand tracking to control DMX moving lights through TouchDesigner and grandMA3, connected via OSC.

Setup:
TouchDesigner + MediaPipe → OSC → grandMA3

In this demo:
The right hand’s index–thumb distance controls brightness.
The left hand’s index–thumb distance controls pan/tilt of the moving light.

Why I use grandMA3 instead of outputting DMX directly from TouchDesigner?

In this setup, I’m not controlling DMX channels directly from TouchDesigner — instead, I’m controlling the control layer inside grandMA3 via OSC.

This approach lets me design and manage all my lighting effects within MA3’s interface, which is especially powerful when dealing with complex DMX setups.

It provides a higher-level workflow where I can focus on the creative logic, while MA3 handles all the detailed DMX mapping and fixture behaviors.

It also makes collaboration with lighting designers much easier — once the control layer is built, it can be triggered by any external input, such as hand tracking, audio, or other interactive systems.
