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

[Vizioen]

can someone please fix the title of this topic please

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.

Can you provide the scene or part of it? So far the new universal approach hasn't let me down. I admit it might render a tad slower, but it was never a huge difference.

Unfortunately i can't... it's under NDA. But it's basically a cave full of scattered rocks and dirt chunks with some glossy reflections. Few portal lights in cave openings to light it up. Vray VolumeFog, dof and motion blur. Primary GI is BF, secondary is LC. It will be animated.

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).

I still believe my UI proposal from a few months back would be the best possible solution to clearing up all this confusion:

But I certainly understand that it's not a trivial change for V-Ray.

After thinking about it...

It's just that, I believe, we are in a transition that hurts, so, to me, it's not just clearing up the confusion, but having a good solution for today while we wait for full automation.

I do think that Vlado's intentions of making V-ray more automatic is interesting. After all, we think we can set the scene parameters better than a computer, but it's a matter of time until the code gets sophisticated enough to decide absolutely everything for us (not the artistic part hopefully).

That's why I suggested to divide Vray in 2. You know: Divide and conquer.

What UI you use for each, I'm not sure how important it is actually. (edit: although your calculator is much more intuitive!)

[Deflaminis]

If we are going more towards automatic it would be pretty cool to be able to select a small area of the image somehow to say it's too noisy and vray will look at the elements for that section for the noise and adjust accordingly.

I reckon part of it is there's multiple ways to achieve things in vray but some of those can mess things up if you don't know what you're doing. There's a very good phrase about doing martial arts where people "know just enough to get themselves hurt" and this kind of applies here. If you half know what you're doing and try manually optimizing a scene you can just as easily cause issues, confuse yourself and get frustrated. The min shading rate approach, while it won't get the absolute fastest time, is at least a bit better at stopping users from killing their render times. With anything I learn I always find that you get to a point where you thought you understood things but then a whole new other world of questions come up and you evolve along with the learning. It's very much the same with vray and people are just at different points along that learning path. Something like the min shading rate approach will at least work for either newer users, less technical users that don't like the idea of working out sampling or people that don't have the time to tune a scene.

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.

Could this approach be used for animations as well? ie calculate all irradiance map and light cache with global set to 1, then when loading from file set back to 0 ?

It means that someone whined a lot on the forum that other render engines worked with this option disabled and were therefore so much easier to optimize. So I added the option as a test, and as expected, they found out that it was not really such a big plus anyways.

My own preferred method for adding more shading samples is through the "min. shading rate" parameter.

The default values for materials/lights/etc are indeed way too high by default, so you'll need to readjust everything.

Best regards,
Vlado

Amen to that.

Yes.

Becaue then artistic people will create art. Not technical people attempt to create art.

Out of all the interesting technical things I learnt on this thread so far this statement is by far the most interesting Only the title of this thread is an absolute repelant for anything artistic, not to mention actually trying to read and undertand the discussion. We are as far as possible from art here my friends, and I will gladly continue to read it all. Thanks all for sharing your educated insights, it helped me a lot clarifying where I stend in this jungle of intricate settings.
