Viewer Node¶
The Viewer node is used to preview image data or value maps anywhere within a compositor node graph. It is a diagnostic tool that allows users to inspect intermediate results without affecting the final output.
You can quickly assign a node to a Viewer by pressing Shift-Ctrl-LMB on the desired node. To switch between multiple Viewer nodes, simply select one with LMB. Only the active Viewer node (highlighted with a red header) will be displayed in the backdrop or Image Editor.

Activate Node (1, 2, etc.): Press the assigned number key to activate the node's Viewer output.
Note
This feature is exclusive to the Compositor and only supports number keys (1-9).
