didn’t see this posted anywhere here yet. It’s from the guy who wrote the book on architectural rendering - literally.
Thank you. 
Great
Great I can’t get enough of Vray tutorials these days - just a quick note is there a link to the scene that I can download ?
Thanks for sharing 
great pdf. Very helpful for anyone.
If you go to the main site, there is a download link to the files

Great Tutorial
Thanks gunny - this is a truely spectacular tutorial, it just wasn’t sinking in before but now that old fog is lifting and I think I’m finally starting to get it :lol: I simply can’t wait for Part II, please give a heads up if you come across it and thanks again
Yeah, this is a really clear and concise explanation - it would be great if Chaos engaged these guys to write a short Vray manual for us… … lets hope.
Pretty cool tut
I dont know if its just me, but it pains me to read stuff like this - something I spent 9 months teaching myself the hard way can now be learnt in a day by someone whos never used it before. :lol:
Guess i’m just bitter that I didnt have this, Its an excellent guide for someone new to vray, haha. (I am only joking, everything I learnt is from these forums and its good to see resources this good being put across through here, I only wish I had the time to make some myself)
yes very clear explications ! 8) Need to be added in the help file!!

:lol: :lol: I agree!!
That said though, I’ve worked with a lot of people over the years who have been trained in by people that were always told the best way to do something straight away and after a while they became totally reliant - they didn’t know how to solve their own problems, where to look or how to learn. You get the same on cgtalk all the time with the same people asking really simple stuff and they’re just going to put themselves in the same situation.
You might have spent 9 months learning it but at least you’ve got a far deeper understanding of it through trial and error as opposed to just doing something because you’ve read it in a pdf.
ive been more into just using it than learning it. but in using it ive learnt about it but i havent learnt everything. even though ive been using it since it 1st was released in alpha stage some hmmm 5 years i think it was ago…there are still quite a few people who know alot more of the theory than me for sure.
rhumm rhumm !!!
I think part 2 is only available if you sign up for a course - cant blame them though, its a lot of work to write that
the best tip in there I found is to only use 2-3 steps in the QMC sampler so min 4 max 6 instead of min 1 max 6
>> ok after extensive testing, that qmc setting does not make sense - its faster to do min 1 max 6 and the quality does not suffer which is what the document suggests
I totally agree about with that as well. I was using Min 1 max 10 with the to get my glossies nice and smooth, and to give the QMC sampler enough room to sample adaptively for good results.
After reading the PDF I tried Min 4 Max 6 settings and it increased my rendertimes with no visible difference in quality
lololololol … i thought the same .. :lol:
Indeed, what would the poor guys at chaos have coded an adaptive sampler for, if people then tend to use it as a brute force tool?
It seems a common enough situation though, to just bash the settings up madly, and wait.
I’d rather spend more time investigating how the adaptive sampler works, myself…
Lele
Maybe they like waiting?. I , however, am much more impatient 8)
The Universal settings method also uses this same principal for those who are questioning our sanity 
>> I just pulled this from the online Vray guide :
" Min subdivs - determines the initial (minimum) number of samples taken for each pixel. You will rarely need to set this to more than 1, except if you have very thin lines that are not captured correctly."
This will be great if someone could definitly clarify this thing.
For me the resume of adaptive mean: less detail less rays more detail more rays, so if I understand well when you put the 1 / 6, 1 is very fast for plane thing without glossy or detail and 6 is more than good for molding (for example).
after that you have to catch the good balance between the two.
Someone could confirm or explain :roll:
Yes, thats the pretty much it. Adaptivity simply means the ability change given different situations ( flat plane - needs few samples, crown moulding - needs more ) In the case of the univesal settings method. The Image sampler will use as many samples neccessary to reach the specified noise threshhold. If anybody can explain that better please jump in
