to output any shader/node output as a custom AOV, you can plug it into a Karma_AOV node, give it a name, set filter type, then plug that into the "next" input of the final Material_Outputs_and_AOVs node in the Karma Material Builder.

Then to render the custom AOV,
In the Karma Render Settings node, Image Output > AOVs (render vars) > Extra Render Vars > add new var and name it with the custom name defined in the Karma AOV node in the material #houdini #tip #karma #XPU #solaris

oh and finally, to debug your AOV pass in the solaris / karma XPU viewport,
On the right sidepanel in the viewport there is a Render Outputs button, that lets you pick which AOV to preview in viewport
