"Devide shading subidvs" leaves Vray working linearly? Is this correct?

[joconnell]

Problem with that is, how do you know when to reduce noise threshold and when to up the MSR?
This is almost too much interaction for universal settings imo

Well, they're two different things really. Noise threshold is what you want vray to work towards quality wise so this value is setting the target for all of the samplers to aim at. Min shading rate is increasing the amount of sampling you're allowing vray to use when aiming to get an image that meets your noise threshold.

Noise threshold for me doesn't change all that often as a creative thing, it's typically just 0.01 or 0.008 for most of my final renders. They get blurred and grain added by compers afterwards to match film footage so I don't need the same level of quality as Kosso_olli does for his high res print work. The only other time my noise thresh changes is when I'm doing test renders as I'll typically put this to anything between 0.1 and 0.5 - what this is telling vray is that I'll accept any crappy standard image which can come out in the very early rounds of sampling and give me quick feedback, think of it as kind of a precursor to having the progressive sampler.

[QUOTE=kosso_olli;624966]The global subdivs multiplier gets set to 0.[QUOTE]

Does this part negate any subdiv values assigned to lights/materials so that all secondary sampling is driven purely by the minimum shading rate?

[kosso_olli]

Yes, indeed. It doesn't matter what subdivs you type in for materials or lights, they are set to zero by the global subdivs multiplier anyways.

This is an interesting workflow... I'm going to try it out soon.

Soooo....

can i get those official Vray 3 universal settings?

Recon, isn't this what you're looking for? it looks pretty official to me...

Credits go to Vlado, he gave the initial hint.

He gives out the occasional useful tip admittedly

Yes, thank you! That's what i was looking for all along.

[Lupaz]

Recon,

when you get a chance, I'd be interested in hearing your opinion about those settings. Thanks.

I've been using this new Universal method + Global subdivs = 0 for a few weeks now and it hasn't steered my wrong yet...

Full Manual Optimization -vs- Universal Settings:

The Universal Settings used to be very limited in the 2.X days, which is what lead to me learning optimization and writing the V-Ray Render Optimization guide.
With the introduction of the Min Shade Rate parameter in 3.X, the Universal Settings are once again a perfectly valid way to approach rendering a scene.

If you're on a tight deadline and need to squeeze every last drop out of your render time, then Manual Optimization is still the best.
But if time isn't a huge factor, or you're just rendering single stills, I'd probably just stick to the universal settings and use the Min Shade Rate parameter to quickly balance the Image Sampler and DMC Sampler.

These are great just tested them and they are blazing fast, but weird, now you're letting your AA take care of everything? Or am I missing something.

Sorry, forgot the most important thing: The global subdivs multiplier gets set to 0. Please see the attachment for my render settings. GI and Light Cache are mostly set at their default, I sometimes raise the LC subdivs, though.

Some results of this workflow can be found here. You can still gain some seconds by using the traditional workflow, but I can't be bothered to do this anymore. The new technique is so much simpler...

[kosso_olli]

Not entirely. By adjusting the Shading Rate parameter you are balancing AA rays vs. secondary rays for glossy reflections, GI, DOF etc.

[LudvikKoutny]

Actually, the very first scene i tried universal settings is already giving me terrible rendertime. So universal settings are definitely not a way to go.

[vlado]

Just a humbled idea: May be there could be a V-ray lite, with universal settings by default without the chance of fooling around with anything, and V-ray Pro with all the options to make adjustments by hand (for which I believe Akin's calculator would be a nice UI).

It has crossed my mind, certainly But I don't know how successful such an approach would be. And I would hate having to support two versions of the UI.
