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 use compositor data here… | Do this… |
|---|---|
| Any parameter that expects an image file. |
Instead of entering a filename, use Warning This will not work in VOPs. The VEX code generated by VOPs cannot do this kind of dynamic image reference. Instead, fetch the image in the shader node (SHOP) that encapsulates the VOP shader network. |
 Trace SOP
|
Creates curve geometry from the color contours of an image. It has an explicit option to take data from a COP node instead of an image file. |
| Color POP |
Colors particles based on the pixel colors of an image. It has an explicit option to take data from a COP node instead of an image file. |
 Image CHOP
|
Converts scanlines of an image from a COP node into channels. You can fetch sub-regions of the image instead of the full image. |
