Overall image sampling - Raytrace renders, like V-Ray, shoot rays out from the camera to sample what is found in the scene to help determine what color each pixel will be in a rendered image. The settings used to adjust how the V-Ray render engine does this, and the relationship between pixels in the render can be found on the Image Sampler (Anti-Aliasing) page. To see the settings for the V-Ray GPU render engine, please visit the V-Ray GPU Setup page.

Image samples pattern - When rendering animations, you can specify whether to lock the pattern, in which V-Ray shoots the image samples, or change it for each frame. Additionally, Blue Noise sampling optimization is used to disribute the samples in a uniform way across the image to help visually reduce noise with fewer samples. In all cases, re-rendering the same frame will produce the same pattern. These options are controlled from the DMC Sampler.
