This page contains information on the V-Ray standalone denoising tool. Overview The V-Ray installation includes a standalone denoising tool called  vdenoise  that can denoise still images or animations outside of 3ds Max. This is especially useful for animations because the standalone tool can look at multiple frames at once and produce a better denoising result. The vdenoise tool is both a command-line utility and a GUI application. It works with either . vrimg  or multichannel OpenEXR files and writes out files with the same format.  You can write those files out of 3ds Max through the  V-Ray raw image file  output options in the V-Ray Frame Buffer rollout. Installation The Denoiser tool is installed along with V-Ray for 3ds Max. To access the Denoiser tool, go to: Start Menu  >  Programs  >  V-Ray for 3ds Max  >  Tools  >  Denoiser Tool  for Windows 10 and earlier. Start Menu  >  All apps  >  V-Ray for 3ds Max  >  Denoiser Tool  for Windows   11. Start the  vdenoise  executable from: C:\Program Files\Chaos\V-Ray\3ds Max 20xx\bin  for V-Ray for 3ds Max 2021 or earlier. C:\ProgramData\Autodesk\ApplicationPlugins\VRay3dsMax20xx\bin  for 3ds Max 2022 or later. Generating the Needed Render Elements The denoiser needs several render elements in order to work optimally. The easiest way to generate these render elements is to add the  VRayDenoiser Render Element  to your 3ds Max scene. Output When the standalone Denoise tool is run, it outputs information about the process, including settings, warnings, progress, and files written in the command prompt window. When using the vdenoise.exe tool the denoised multichannel output is now  lean  by default. The extra denoiser data is not included in it. Save denoiser extra data  – Enabled by default in V-Ray raw image file output dialog inside 3ds Max. This option ensures that all denoiser channels are available by default in the raw output so that they can be utilized if needed when using the Denoiser tool. Example: Save V-Ray raw image file from 3ds Max (Save denoiser extra data toggle on by default). Load the output in the vdenoise tool. It outputs a denoised image without the extra channels included by default (lean output).
