Glow causes denoiser to fail

Checking glow in post render effects causes NVIDIA denosier to fail.

Actually, I noticed yesterday that all 3 denoisers only worked intermittently.
IE, when rendering out PNG frames it would work at the beginning of the animation and then fail intermittently as it progressed.

Hi @3dsynergy,

I’m not able to reproduce the issue on my side. What version of Rhino 7 are you using, and what version of the NVIDIA Denoiser? Can you reproduce it every time? If so, please give exact instructions on how to reproduce after having started Rhino.


@DavidEranen could this be a case where GPU memory runs out, considering the GPU model in use: GTX 960M.

Hi @DavidEranen

Yes, I can,
Render a file with the denoiser on and that works well for me
Then I click on the post effects and insert a glow
This for me causes the denoiser issue every time. If I use bloom that works and so does fog and depth of field.

Thanks for your help and fast response,

Hi @3dsynergy,

I noticed that your NVIDIA denoiser version is 0.4.0 - please update to the latest version which is 0.4.2. What resolution are you rendering at? What happens if you move the NVIDIA denoiser to the top of the post-effect list, so that it executes before the Glow post-effect. Does that fix the problem?


Hi @DavidEranen
I just installed the newer denoiser and all is working with one caveat but maybe I’m expecting too much.
If I do a rendering with the denoiser on and then after it finishes, I add a glow the denoiser throws the error I reported earlier. If I add it before rendering then it works and I can turn it on and off without it causing the denoiser to error. I recall in previous builds we could add a glow either after the rendering finished or before rendering.


Thanks - I can reproduce it using your latest instructions! I made a YouTrack item and will investigate (


There is a new version of the NVIDIA denoiser available (version 0.4.3). Please update it through the PackageManager and let me know if it works better now.


Hi @DavidEranen,

Thanks I’ll put it through it’s paces and let you know how it goes.
Appreciate your help and work on this cool feature.

Hi @DavidEranen,
I updated the denoiser via package manager to (version 0.4.3)
It seems to be working I can add the denoiser pre or post rendering and I don’t get the error.
Thanks for your help,
