Old network
As of Houdini 20.5, use Copernicus nodes instead of Compositing nodes. Though both networks still exist, the Compositing network is now designated as COP Network - Old. The Compositing network and its nodes will be deprecated and then removed in a future Houdini release.
An image guide file is a text file containing one or more drawing commands which describe guides to overlay on compositing images.
-
In a compositing viewer pane, open the right side toolbar and click
Display Options or press D to open the Display Options window. -
Click the Viewport tab.
-
Use the Image Guide option to set the image guide file to use.
