Houdini 21.0 Compositing

View/preview the output of a node

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.

To...Do this

View the output of the node in the compositing viewer

Use a background image in the viewer to help you judge opacity

  1. In a compositing viewer pane, open the right side toolbar and click Display Options or press D to open the Display Options window.

  2. Use the controls on the Background tab to load a background image.

View the output of a node as a flipbook in MPlay

  • Press on the node tile in the network editor and choose Flipbook. You can also flipbook reduced resolution versions of the image.

    You can press ⎋ Esc to cancel the generation of the flipbook.

    You can save the flipbook frames by choosing File ▸ Save Sequence in MPlay.

Keep the output of a node visible in a floating window

  • Press on the node tile in the network editor and choose Preview Full. You can also preview reduced resolution versions of the image, or an icon-sized thumbnail.
