  • Shit Grant this warez stuff is beyond belief, name and shame the $hithead,
    I havent even got a chance to download anything yet, i'm planning to get shuck in early next week.

      • I look forward to the video. I am sure I have more to learn then I actually know. I try to keep my subdivisions below 24. Now, I do interior and exterior architectural rendering; does the 128 subdivs apply to large scenes?

        If you are only using 32 subdivs on shaders, Vrays antialiaser is doing far too much work!

        All will be explained in the intro video.

        • Think of it like this.

          Noise causes large differences from pixel to pixel
          Large differences in pixels makes Vrays anti-aliasing job a LOT harder.

          So by making sure your materials have enough samples to eliminate noise you are making Vrays job at antialiasing the image MUCH easier.

          It just so happens that Vray needs values like 256 to remove noise with glossiness below .8


          So what you are left with is a very clean and fast rendering image because the anti aliaser is only working on geometry edges and the edges of specular highlights, NOT the whole image!

          • Makes sense. So, higher material settings + lower rendering settings = faster and cleaner renders?

                If by "rendering settings" you are referring to the antialiasing then basically yes. HOWEVER

                not all jobs need high AA and this is where Akin and I are on the exact same page.

                The annoying thing is, once you figure out the correct material subdivisions to clean a scene and move onto changing the AA settings, you are forced to change the material subdivs again!
                Akins thread proposes to unlock the two so you can independently control AA and Sampling, IMO a very awesome idea!

                Vray is built by math geniuses and sometimes this comes across in the way the UI is set up.
                Is it mathematically a great algorithm? Absolutely as its designed to balance AA and sampling but it's not great for anyone but users who have a DEEP understanding of how to decouple AA from Sampling.

                      Starting to go OT, but in that post the cleaner render is nearly double the render time, so although it is cleaner it also takes longer which is what I'd expect. Is it a case of "it'll take longer, but nowhere near as long as doing it incorrectly"?

                        Yes.

                        This is the render with 1/8 AA and 100 subdivs for the light and material. (1m 7s - cleaner and faster render)
                        http://www.cggallery.com/temp/forums/02_p8_s100.jpg

                        And this is the render with 1/100 AA and 8 subdivs for the light and material - AKA the so-called 'universal' V-Ray settings. (1m 11s - noiser and slower render)
                        http://www.cggallery.com/temp/forums/01_p100_s8.jpg

                        There's plenty of info covering this in the Understand DMC Sampler thread if you want to learn more.

                          I'm pretty sure Akin didn't spend more than 2 minutes setting up that scene, he was trying to show how Vray balances things.

                          You can absolutely 100% decrease render times while increasing quality. FACT>

                            • Thanks for the link Akin,
                              did a small test setup and its great to see quality go up and render times go down.
                              what have i been doing all this time
                              will read up on thread with a cup of coffee in the morning

                                In maya, use "create from vray plugin/texture". And you have all the bercon maps right there...
