Preview Node

Description

This node enables you to inspect a preview at a specific point in a Shader Graph. 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, you can manually select your preferred preview mode.
