global control for light material

[zeronove]

I find that for testing and trouble shooting issue, it could be very useful to have a way to control globally the vraylight material (to avoid searching among zillion of scene materials).

My first ideas about locations are:
- a checkbox inside global switches rollout (maybe below hidden lights)
- as a list inside vray light lister

Well that's why we have the mesh lights...

mmh, good point ..as usual
but how do I achieve a GI only setup using mesh light?

[super gnu]

use the "store with irradiance map" tickbox.

use the "store with irradiance map" tickbox.

mmh, so a meshlight with "store with irradiance" checked is the same that a light material WITHOUT "direct illumination" checked, correct?

[super gnu]

that is my understanding yes. maybe there are some differences beyond interface, but chaos would have to comment on that.

In terms of final results, it should be the same, yes.
