My Current folio: http://sathe.cgsociety.org/ [image] Update! - 22/11/13 (Australian time) I am now offering pre sales to those willing to purchase early in order to make the first 50. I’ve had over 15 people ask if they can do this. Please email me to confirm your order admin@sathe.com.au Thanks, Grant. Hi guys, Many of you asked for some form of shading and lighting tutorial over the years however I never got on it due to trade secrets I developed while working at Lightfarm and the advantage it gave them. However, with my brother managing me I’ve been organising an extensive completely in depth masters class for Vray for use in production targeted at large studios and advanced users. I need your guys help deciding on complex materials to recreate that I will develop into the package. Anybody who pitches a material / or materials to me, including attaching reference images to this thread, that I use in the production will receive the shader for free when packaged into my series. I’m talking physically complex materials that have properties others have struggled to reproduce. (Cracked ICE, Magma, Food) www.sathe.com.au Stay tuned! A sneak peak at some of the materials I will cover creating. (These behave correctly in HDR light studio, daylight and night time lit rigs so far. more examples to come soon) -Multi layered Anodized, anisotropic metals with procedural scuffing, mottling. -Brushed metal with split RGB Exponent for simulating chromatic aberration and ringing around highlights (Used in Iron Man shaders) - Advanced procedural car paint with dust, scratches, dirt and flake simulation - Physically accurate Gold and Metals with nested fresnel layering to simulate complex BRDF highlights and grazing. Stay tuned and thanks for your help in advance. Note- all renders are untouched and have no post production or color correction.

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?[quote=“adamf13, post:10, topic:43357, username:adamf13”] Think of it like this.

[image]Vray transfer to 2013 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. (Using Akins DMC calculator)

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”?

[image]spline to nurbs curve 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. :slight_smile:

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.
