Hello,
I must say, I'm very impressed with Corona renderer. It's so straightforward I've got it up and running in 2 mintues with object light, displacement etc... I use VRAY from time to time, and I admit I have to search for parameters in help file, everytime I have a longer break from this render engine.
Attached is rendertest with some post glow. All light is emitted from textured boxes.
I've got also a question: is activeshade impremented already? It crashes Max 2013.
Cheers,
Piotr
