Hello!
I was reading about temporal denoise and other stuff, and remembered about this article: https://support.chaos.com/hc/en-us/articles/4411161850897-Using-the-standalone-Denoiser-tool-VDenoise-exe. It explains about it and points to the standalone denoiser tool.
The thing is that I couldn’t find the tool in the Blender folder where it points, even having VRay installed for Blender 5.0.1 and Blender 5.2 LTS.
(C:\Users\\AppData\Roaming\Blender Foundation\Blender\\scripts\addons\vray_blender\bin\VRayZmqServer\appsdk\bin).
The documentation doesn’t include Blender along with other applications.
Denoiser Tool - V-Ray Tools - Chaos Docs
On the other hand, I also have V-Ray for Maya, and the denoiser tool is in its folder with the name “vdenoise.exe”.
Is this expected? Does Vray have only one instance of the denoiser tool or should it come for each dcc that I have vray installed?
vdenoise.exe should be located at:
C:\Users\Bozhidar\AppData\Roaming\Chaos\V-Ray for Blender 5.2\bin\VRayZmqServer\appsdk\tools\vdenoise.exe
However, after trying it, it seems to be quite broken. It cannot find its DLL files, and fallbacks may be kicking in. For example, selecting the NVIDIA denoiser might fall back to the Intel denoiser. If you want to use the NVidia denoiser specifically you probably need to copy it in bin i.e. C:\Users\Bozhidar\AppData\Roaming\Chaos\V-Ray for Blender 5.2\bin\VRayZmqServer\appsdk\bin\vdenoise.exe
Side note: I would recommend installing Everything. With it, you can simply search for vdenoise.exe and will find all vdenoise.exe files on your computer.
Humm this is strange.
I used the path you shared, but all I found was a file named .agreementsAccepted74000 and nothing else. There’s no \bin there.
Everything is on the Blender folder, except for the vdenoise.exe file.
C:\Users\Julio Arvellos\AppData\Roaming\Blender Foundation\Blender\5.2\scripts\addons\vray_blender\bin\VRayZmqServer\appsdk\bin
Did you look for it inside tools like I suggested above? I see it in tools on a completely fresh install. It should be inside that folder with a bunch of other special V-Ray tools. What I meant is that it might not work well at the moment with the NVidia denoiser and might need to be copied in the bin directory.
Yes, I did, but there’s no tools folder inside \Chaos\V-Ray for Blender 5.2. See the recording:
I’m using V-Ray 7.40.00 rev 614 from july 20 2026. Installed it from the Nightlies page.
Oh sorry I mislead you… We are changing the installation directories a bit and I was testing with nightlies where V-Ray for Blender get installed in %appdata%/Chaos/ and I mindlessly copied the directory.
For you it should be in a similar directory to C:\Users\Bozhidar\AppData\Roaming\Blender Foundation\Blender\5.0\scripts\addons\vray_blender\bin\VRayZmqServer\appsdk\tools
No worries! But still there’s no ‘tools’ folder. I’ll reinstall vray from the nightlies and check if it fixes it here. Will let you know soon!
Hmm okay, there’s indeed no tools folder with the last release… Wonder where mine came from
You can use the one from your Maya installation for now, they are practically the same. We will fix it for next release.
Yeah, I reinstalled it and even tried the unified installer, but nothing changed. Will use the Maya one.
Thanks for checking it!
