Here is a test of the the Goe-light in Vray. I have to say that I am VERY impressed with this feature.
There are no other lights in the scene exept for the lamp shade. Also, no environment. Also, no work to the actual shade yet, just a light material for now.
The image took 5 minutes to render at the default subs of 8. The IR was set to low, and only 200 subs for the LC. DMC set to 1/2
I have been testing this for stills, and I think it will work for “moody” type scenes. I have to say, from the tests (about 10) this works alot better than I thought it would when I read about it.
Here is another test with better settings.
IR set to med. LC set to 900. DMC set to 1/6. Subs on the geolight 32.
Still pretty fast, and almost clean enough for stills.
