To play these .tox files in LightAct you would use Play TouchDesigner Component nodes.

**Good to know**: when you select a TouchDesigner asset in the dropdown, it takes a minute or two to load TouchDesigner component.

When TouchDesigner component loads, the node updates itself with new input and output pins and is ready for use.
