Why do you keep posting photos like this?
Weird the vray guys ate this stuff up for lunch with a optimistic heart oh well you can't make everyone happy that can't appreciate complex indirect light.
Not sure what there is to "eat up" about these. I guess you're here to provide us reference material as some sort of "service"? Oh well... you can't expect everyone to be happy about random photos of caustics.
I sure like some nice caustics, and these are good examples, but KeyShot is already able to render these, and more complex for that matter. :)
