SurfaceLuminance Vray Attribute option

[mkinfouss]

Hi,

I was working on some Lookdev setup until I realize that surface luminance was extremely limited to do any mask operation.
The current options/luminance mode are really useful but we can surely push that node to another level:

Would it be possible to allowed LightSet selection so we can use multiple surfaceLuminance node to make operations between them.
right now because there is no such option, making operation forced you to render different AOVs (or eventually bake the end result through different layers) and make operations in a compositing
software before sending it back to Maya.

Hi, thanks for posting. I will see what we can do about this idea.
How about using Light Path Expressions? It is a bit more challenging to setup but I think it could work.
