I want to desaturate an image form colour to black and white within Houdini. I understand this can be done in a COP2 Network. WHich node would I use to desaturate and which parameter do I adjust?
The image is an HDRI to be used in an Environment Light, so I assume this is the method to use.
How to desaturate image in Houdini (COP2 Network)?

Hi,
You can use the HSV COP:

Thanks, how do you show the image in the viewport? Composite View presumably?
OK Got it to work. Thanks.
It shows a desaturated image in the Composite View OK.
If you cook the COP network node, it should show the result in the viewport.

How do I stop the COP2 Network image showing in the Scene View? Presumably I have to put it inside a Geometry node and deactivate its display flag?
You can display another node like a null node.
