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.

Tip

Blur, Defocus, and Sharpen can use a matte to control the per-pixel effect amount (black is no blur/sharpen, white is maximum blur/sharpen).

Tip

The Transform COP and all compositing operators that have a transformation option let you add motion blur to the transformation.

To do this…	Use this operator
Blur	Blur COP
Blur edges	Edge Blur COP
Simulate camera blur	Defocus COP
Simulate fast, uniform motion	Streak COP
Radial blur toward, away from, or around a point	Radial Blur COP
Motion blur	When animating transformations using the Transform COP or the compositing operators with a transformation option, you can add motion blur to the transformation with the Motion blur parameter on the Transform tab.
Sharpen features of an image	Sharpen COP Increase the kernel size to sharpen larger features. The kernel size controls how many surrounding pixels to consider when the node calculates local contrast. Use the Noise parameter to prevent the node from sharpening grain and other noise.
