These additional rays are called Secondary Rays and are controlled by V-Ray's DMC Sampler.Ī simplified diagram of raytracing: Primary Rays are sent out from the camera into the scene, intersect with geometry, and send out various Secondary Rays to sample the scene.įrom this point forward, we'll simply refer to 'Rays' as 'Samples' - because that's what the purpose of a Ray is - to take a Sample of a scene to gather information about what's going on in it. Whenever a Primary Ray intersects with geometry in the scene, additional rays get sent out from that point of intersection into the rest of the scene to gather information about things like Lighting, Shadows, Global Illumination (GI), Reflection, Refraction, Sub-surface Scattering (SSS), etc. These rays originating from the camera are called Primary Rays (sometimes also called Camera Rays or Eye Rays) and are controlled by V-Ray's Image Sampler (Also known as Anti-Aliasing or AA). When a render begins, rays are first sent out from our camera into the scene to gather information about the geometry that will be visible in the final image. If you already know the underlying concepts and just want the technical step-by-step procedure, you can skip right to it.

And finally I'll provide a step-by-step procedure to optimize any scene to render with an ideal balance of quality and speed.

Then we'll learn how to identify the different sources of noise a scene can have. Then we'll go over an example scene to demonstrate exactly how a render can be optimized to be faster and cleaner. We'll first cover some of the underlying concepts behind how rendering and V-Ray's sampling works. But with a bit of understanding of how V-Ray works under the hood, you can achieve a higher quality result WITH faster render times - in some extreme cases ranging between 3x faster to 13x faster than the universal settings. Many times you'll see artists adopt the 'Universal V-Ray Settings' of having the Image Sampler (Anti-Aliasing, or AA) Max Subdivs value set very high (like 50 or 100), and then simply lowering the noise threshold value until the render becomes clean enough - thinking that it's the best / fastest that V-Ray can do.

There's often a lot of confusion surrounding the topic of V-Ray's sampling and what 'ideal' settings are. You need to twirl open the 'Global Illumination' tab and share that as a screenshot, because there are important settings in there for troubleshooting this specific issue.This tutorial attempts to cover and clarify the process of optimizing your V-Ray render settings to get the best possible render quality and fastest render time for a given scene. Also, under that setting you have it set to 'medium.' have you set that to 'high?' That is the floor for what should ever be necessary, if you still have noise at this point, the problem is elsewhere. If the wood grain pattern only has like 4 pixels to define all that detail, it's going to look mushy. The reason is that 866x450 just isn't enough pixels to clearly and cleanly render detail. If you actually need the final image to be 866x450, I would suggest rendering at double that size (1732x900), then scaling the render back down to your final size (866x450) in Photoshop. I'm not sure why you are rendering at that specific resolution (866x450) but make sure you only ever review your renders at 100% of their actual size. In other words, you've rendered this image very small and are zooming in on it 2X for viewing, which is always going to make your image look bad. first of all, you are viewing your image in the Vray Frame Buffer at 200%.
