If you copy these .tox files into Assets/TouchDesigner folder they will appear in LightAct.

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.
{% endhint %}

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

## Prerequisites

In order to be able to play TouchDesigner components in LightAct you need:

1. a TouchDesigner commercial or above license
2. TouchDesigner installed on your machine.

## Other considerations

{% hint style="warning" %}
**Multi-gpu systems:** TouchDesigner integration on multi-GPU systems is not supported at the moment.
