Overview

The V-Ray Denoiser takes an existing render and applies a denoising operation to it after the image has been completely rendered out via normal means. The denoising operation detects areas where noise is present and smooths them out. Images can also be denoised using the Standalone Denoise Tool included with the installation of V-Ray for Nuke.

Because the V-Ray Denoiser operates on other render elements rather than being part of the rendering process itself, the denoising operation does not require rerendering of the scene.

The V-Ray Denoiser has three preset options for its settings: Mild, Default, and Strong. Parameters can also be adjusted directly by using the Custom preset.
