# Controlling Layers with OSC

<div align="left"><figure><img src="/files/lVKzDoWspuWVcbFfWg27" alt=""><figcaption></figcaption></figure></div>

All variables that have a small **OSC** button can be controlled via OSC protocol.

This can be achieved in the **OSC In** window where if you click on **Regenerate** button, every Layer variable with OSC flag set to True, will get a unique OSC address.

When an OSC message with the correct address arrives, the green circle will light up.

In Layer Properties the OSC flag of that variable will turn green and the variable's value will get set.
