Need a V-ray primer, haven't used since v1.5

Would any of you have suggestions on how I can quickly get back on track with Vray 3.2? I just upgraded and haven't really used it much since v1.5 (I've been using Mental Ray for quite a while now). I'd rather not sit through hours of basic V-ray training as I had a pretty good grasp on V-ray back then.

 

Some things I'm interested in are basic render workflows that avoid most common render errors and aberrations (like grain and specks), and how to get a good AO render for compositing. Also, do the V-ray render elements like MatID and ObjID work well for compositing in Photoshop now? I have not tested any of this yet but in the past I used to get a lot of aliasing when using those as masks in Photoshop.

 

Anyway, if you guys have some suggestions on how I can get back up to speed (other than reading the manual and the last five years worth of Chaos Group forum posts) I'm interested in your input.

 

Thanks!

Before anyone suggests tons of tutorials...some great, some great within specific context only, some unnecessary,etc..

 

I'll simply suggest to use the current/new 'defaults'. Rendering has generally moved on from fiddling with numbers, although fair crop of old-time fanatics love to kindle with it, Vray caught with times as well and the defaults simply work. They work well.

 

That means not touching anything outside of your desired resolution, noise threshold for preview/final quality distinction and choice of passes. Press enter and voila.

 

And then there are some even easier renderers..

Thanks Juraj. I guess I'm being a little lazy but yeah, eventually I'll get into the nuts and bolts of the manual. I just remember what you were describing, endlessly tweaking arbitrary numbers just to get rid of some fireflies or other artifacts.

I am trying to find the video Vlado posted very recently where he shows his current workflow and comments on it...it's quite good but my memory fails me and it's not on official chaos' youtube page : / I'll add it here if I happen to find it.

 

But basically if he could strip some of the settings (like samples), he would.... and he keeps it as simple as possible.

 

But ChaosGroup did amazing job with the two recent service packs. They added recently improved sampler that's even more autopilot for complex archviz scenes, and various other little features here and there. It's not one-click solution...but it's not 100 clicks either unless you heavily want. And that's great as they found a way how to appease both type of users. That's still confusing and I like things even more simple but it's great direction overall nonetheless.

Yes, MtlID still works for photoshop...the way I use it at least. They did add a nice mouseover feature that describes the setting and what raising it and lowering it does. In terms of noise and splotches, the old workflow I think still works. IMHO, the "It" thing to do now is use gamma correction and getting it set up correctly. Tons of tutorials out there on youtube.

Having correct gamma was always sensible but it does "not" need to be setuped. Because the current default is correct and doesn't allow you to mess it up. Even 3dsMax is setup correctly from 2014+ version.

Vray 3.2+ is set in linear fashion from get-go and you can further influence whether you want it to also affect sampling (by default set ON) and baking into result (by default set OFF). Nothing needs to be done, nothing needs to be touched. All the ridiculous tutorials from past can be finally ignored and no one needs to wonder what is LWF anymore... because that discussion was always painful.
