# Preview Node
|
||
|
|
|
||
|
|
## Description
|
||
|
|
|
||
|
|
This node enables you to inspect a preview at a specific point in a [Shader Graph](index.md). It does not modify any input values.
|
||
|
|
|
||
|
|
By default, the Editor automatically selects a preview mode. That decision is determined by both the type of the node you are previewing and other upstream nodes.
|
||
|
|
With [Preview Mode Control](Preview-Mode-Control), you can manually select your preferred preview mode.
