Every big interactive project runs on TouchDesigner, and every TD developer knows the messy part: a bespoke patch, a control panel built from scratch, and an install the next person can't maintain. Lightpath is the scaffolding. You build only what's unique to your install — patterns, outputs, sensor logic — and inherit the entire operational layer out of the box.
You never have to pay for Lightpath. The client pays licensing fees directly, and you set your own margin on top. That turns every install into a new form of recurring revenue for your studio.
