Nvidia AI Denoiser Error

V-Ray V-Ray for 3ds Max Issues
1

In 3ds Max 2019 I am getting an error with the Nvidia AI Denoiser after completing one successful rendering. In 3ds Max 2018 I don’t receive an error, however, the Nvidia AI Denoiser will not complete after the first successful rendering attempt. The Attached Image shows the error I receive when rendering is 3ds Max 2019.

Can you tell me what is your graphics card and driver version? Also does it happen on any scene, or just this one?

Best regards,
Vlado

Quadro M5000, 391.58. I tested a couple a different scenes.

1) Scene was created with Previous Version Vray 3.60.04 and 3ds Max 2018 or prior, Heavy Scene, lot of High Poly Count content, no vray proxies, Large Scene File Size 4gb, High Resolution Rendering 6912x3456 - One Successful Rendering, Subsequent attempts error out.

  1. Scene was created with Previous Version Vray 3.60.04 and 3ds Max 2018 or prior, Heavy Scene, High Poly Count, Vray proxies, medium size scene file size 400mb, Moderate Resolution Rendering 3648x2432 - One Successful Rendering, Subsequent attempts error out.

3) New Scene 3ds Max 2019, Default Vray Next Rendering Settings with the exception of Vray Denoiser w/ Nvidia AI Denoiser and Resolution, Feather Weight Scene (One Box, Vray Plane, Vray Dome Light, Vray Physical Camera) - Several Rendering Image Passes will occur during rendering(+15), effectsResult element will appear in frame buffer, several passes will continue after and when complete I will get a black Frame Buffer or Denoiser Error.

4) New Scene 3ds Max 2019, Merged Rendering Setting from Scene example 1(Resolution 6912x3456), Feather Weight Scene (One Box, Vray Plane, Vray Dome Light, Vray Physical Camera) - Renders 2 Image Passes, effectsResult Element Appears after Passes and Bloom Apply completes, No Denoiser errors, I can render multiple camera views without having to close out of 3ds Max.

Hey Guys,

A follow up, I wanted to let you know I was able to resolve the issue by rolling back my Nvidia drivers.

It was a tedious process this morning but I went through and installed every previous Nvidia driver one by one until finally one worked all the way back from December.

The first one to work was : Version 388.71 – WHQL | Release Date: Wed Dec 20, 2017

I hope this saves the team some time and helps others that might have a similar problem.
