Per-Lobe Lightgroups

Hi,

I'd love to see per-lobe lightgroups in Cycles. At the moment the light groups are set up so that they are an extra pass within the beauty render. What my workflow currently uses is individual renders per light group each with their own unique diffuse/indirect/glossy/etc

I have a workaround setting this up manually but from what I can see this has two downsides. Firstly to time it takes to set it up. And secondly it seems that given the amount of lights changing in each render the sampling comes out wildly different. This means that rebuilding the beauty can sometimes be impossible because the sampling of a specific light in the beauty will be far lower than in the individual pass. This is something the per lobe groups should solve.

This is also something that nearly all other render engines has available so getting this in cycles would be another step in helping others adopt cycles more easily.

Thanks, Mitchell
