Selection object and light inclusion/exclusion

[edenexposito]

Feature request:

It would be nice that Arnold light project inclusion/exclusion would work with elements placed into "selection object" ( Selection -> Selection Filter -> Create Selection object).

I mean instead add objects to Arnold Light Project directly, add pre-made groups (selection object) to project section. Seems not be compatible by now but it would be super useful with complex projects.

With this method would be possible create a selection object called "metal" with all metal parts placed inside it and other selection object called "plastic" and assign only these two objects instead a lot of pieces placed inside complex hierarchy every time that I need include/exclude from light.

Simple example:

I have to check how to access the data of the Selection object via the API, but should be doable.
