3.2 Denoiser Improvements


3.2.1 Denoise render elements

With V-Ray Next, you can denoise every render element separately for better compositing.

  • Render the image and save it in the VFB history
  • Go through the render elements to observe how only Beauty Pass is denoised. The rest of the render elements, however, are not
  • Go to the render settings and select the render element(s) you wish to denoise
  • For example, choose the reflection
  • Then tick the denoise checkbox, located at the bottom of the render element parameters
  • Render once again and compare with the previous result

3.2.2 Standalone Denoiser Improvements

Now let's take a look at how to denoise animations with the improved V-Ray Standalone Denoiser or also known as Denoiser Tool 4.0.

The Standalone Denoiser uses adjacent frames to create a smooth denoised animation with no artifacts.

  • First off, you can expand the “Advanced denoiser parameter” tab in the “VRayDenoiser” render element and set the mode to "Only generate render elements". This way you’ll skip the denoising process during the actual rendering and save some time
  • Then go to the “Frame Buffer” tab in the rendering settings and select an output file (V-Ray raw image file)
  • Use either OpenEXR (.exr) or V-Ray image file (.vrimg) for the file format
  • Then enable animation and hit render or use the provided pre-rendered sequence from the “Rendering” folder
  • Press Windows “Start” button and type "Denoiser Tool 4.0" and run it
  • Browse the sequence from the rendering folder
  • You can also choose to denoise separate render elements
  • Once ready a new set of denoised images will appear in your sequence root folder
