Visual Compositor

Visual Compositor is a GameObject component for executing a node-based graph defined in a Compositor Graph asset to produce the final render output.

Property	Description
Compositor Graph	The Compositor Graph asset to be executed.
Main Camera	The default camera that will be assigned to newly created nodes in the Compositor Graph asset.
Output Size	The size of the final output.
Display Mode	Specify if the final output should be rendered in linear or sRGB color space.
Background Color	The background color.

Editor optimization

Disable non-VC cameras button is used to disable camera components in the scene which are not attached to Visual Compositor.

This will optimize the Editor performance because Visual Compositor executes the rendering internally as part of the graph execution, and therefore does not need the output of camera components in the scene.
