rendering VRayDenoise command line causes erros preventing network render

V-Ray V-Ray for Nuke Issues
1

Hi,

when rendering a nuke script that includes a VRayDenoise node throws a bunch of warnings that seem to be interpreted as errors by Deadline, and thus prevent network rendering.
Edit: This is with default settings in the VRayNoise node. I tried it on GPU and CPU:

When rendering a frame through the UI I get the below output in the terminal:
Reading Input Frame: 1001.00
Reading Input Frame: 1001.00… 97.2 %

When rendering the script via command line I get this:

Deadline just barfs at this.

Any ideas what is causing those warnings/errors and how to bypass this?

Cheers,

Hello,

This is just a warning that we output when using the Denoiser, similar warning should appear if there is V-Ray Translator in the scene as well.

As for Deadline - did you try to turn on “Continue on Error” in the Advanced Options? If this doesn’t help probably Nuke has some kind of way to disable the warning in the log and show only errors.

I assumed as much but it does seem to prevent Deadline from working. Will investigate some more though, maybe it’s unrelated after all.

Probably the Deadline guys can help you resolving this problem.
