This work I did for myself, to understand, how works the new VRay 3.0.07.
I was rendering with different ways and trying to find the best settings for nice clean pictures and calculating time of those pictures.
Brute Force+Light Cache, BF subdivs -128, light subdivs - 32/64, colculating time of one picture - 3 hours ( progressive method ), 1,5 minutes one pass.
This is my first post on render.ru and i will be very happy to join the community :)
