Sampling for Arch Vis renders in vray 2.4

great tutorial, thank you!

Thank you for this huge job, it helps a lot.

I would have placed a skylight portal in that opening and saved myself a huge amount of time. Yes I know the discussion was about samples and demonstrating what they do and what affect they have on the scene.. but for any interior render, sky portals are a definite must. otherwise as you point out, the initial image, will look awful from the get go, since Max / Vray haven't got a clue where you actually put holes in walls for light to enter, therefore wasting a huge amount of the samples, outside of the scene, lighting parts you will never see.. Interesting use of render elements though, will definitely take a look at that later.
