DeadClown, we worked with the old VRay UI for 10 years. Obviously, for us, now it isn't comfortable. But they just reposition some options.
About the calculator, Chaos Group need an official, CLEAR explanation. Because, for me, it was one of the arguments that it sended me far away from V-Ray.
I hadn't time to read 10 discussion with 80 pages about noise in VRay produced by wrong settings about AA, subdivs, noise threshold, control render elements.
I remember, one or two years ago.... A veeery long thread about noise. Every user said own opinion. And no one official replied by Vlado.
it was unprofessional, and now, if you read the general section on Chaogroup forum, there are so many discussion about the same argument...
Pfff... I hope Corona will not follow the same direction.
