Emission AOV by light group

Hi There. I'm having an issue with getting lights to appear in the emission AOV when selecting "All Light Groups"...

In my screenshots below... the light group "LED_Strips" is being picked up fine in the beauty AOV light groups, and its also picked up fine in the general emission AOV, but nothing in its emission light group.....? It's a visible mesh light. Am I missing something?

Sorry, but light group AOVs for emission are not supported yet.
For reference, this is logged as ARNOLD-9436

Ok thanks Stephen. Do you know if there’s any kind of workaround to get an emission AOV for a specific light?

In case of a mesh light, you can have an object mask on the mesh and use it in post to identify lights in the emission AOV.

it's still a big issue that the emissive mesh is not added to RGBA_YourLightgroup AOV and Emission AOV. This problem is with visible mesh and area Lights and should be fixed by the developers.
