The way i answer may look insulting i agree, that's just because i'm quite sick of seeing the same kind of answers since i started reading forums: ancient members grunting at younger because they don't want to spend hours learning theoretical stuff.
I work in cg for almost one decade, i didn't do any school so all I know comes from the internet and friends, I work 8 hours a day so i don't have the time to read the vray doc, the 3dsmax doc, the zbrush doc, and so on. I have a job to do, and I try to find the best way to do it without wasting my time.
Your opinion may be right, knowing what's behind a button is interesting, but i'm ok with just knowing which button to press if i don't need more.
My puprose is not to know all about vray, I just want to know how to use it correctly.
I apologise for my previous answer, but what I saw in your answer was something like "i spent hours reading vray doc to know what i know, so there is no reason why you wouldn't do the same"
Just one example, my question was about the necessity of managing subdivs manually, to me it's much more useful that somebody tells me it's useless, than reading tons of pages that I barely understand to try to find the answer. Furthermore, this kind of tips is rarely in the doc. That's also the purpose of teaching in general, and of this kind of forum: synthetising knowledge.
cheers
