Hi,

If I have the workflow for geo lights in Karma correct, one uses Render Geometry Settings to set the 'treat as light' attribute, then I can also set up the LPE for it at the same time.

However we don't get a per-light AOV for geo lights with the regular Karma Render Settings LOP as it only cycles through light primitive types. In the attached example I just manually set the light path from one light source as a test so it would just be a matter of cycling trough mesh types as well as lights. Perhaps this could be an RFE for the karma Render Settings HDA, or is there another way to get light AOVs from geo lights?

Oh, maybe it's not that practical to have it as an option by default. I just recreated the same workflow from the Karma standard vars and filtered by name *LGT_GEO* so as not to go crazy. Would there be a way to filter the for loop by the existance of a primvar?
