I've always wanted to make a scene with a very bright lighting.
And that's it. I've used vray skylight, and what is very imprtant, vray lights in windows to add more bright and modify the color.
Very usefull option, to achive this level of white, was possible with white balance in VrayPhysicalCamera.
I hope You like this mood. I wish to thanks to my lovely Margaret for inspiring me much. Comments are most welcome
