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 ray tracing 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 V-Ray's sampling methods and what 'ideal' settings are. This tutorial attempts to cover the process of optimizing your V-Ray render settings to get the best possible render quality and fastest render time for a given scene.
