So here’s a quick run through of the process I normally use when sampling scenes within vray. It’s based in 2.4 but it’s the same process of using overrides and render elements to check is each aspect of the image clean each time. The scene is not meant to be a pretty picture or a finished scene in the end, it’s just a run through of a fairly typical and also quite nasty scenario as regards sampling of lights and materials in vray.
