Thank you so much again Tomas!

I appreciate your explanation. I have tried it and it works.

In an older version of Houdini I was able to reduce the saturation of the image in Copernicus and link that to the Environment Light, however can't get his to work properly in Houdini 20.5.

are you talking about not being able to get op: syntax referencing COP to work for environment light?

Hello Tomas, yes that is one uncertainty. I had connected the HSV node to a Null node in Copernicus and dragged the Null node in to the Environment Map field of the Environment Light but it did not seem to work even though syntax appeared. Perhaps I need to manually type in some specific syntax to make the connection? Not sure what this should be.

I want to desaturate a colour HDRI to B&W to use for the Environment Light. In an older version of Houdini I was able to reduce the saturation of the image in Copernicus and link that to the Environment Light, however can't get his to work properly in Houdini 20.5.

What is the method?

Or if I instead export the converted image from Copernicus, how do I do that exactly? If I have this correct, do I link the output node that makes the correction (HSV Adjust) to a ROP Image Output node in it's COP Path by dragging the node in to this field?

Playing around this is how I set up the export -- is this the way to do it?:
