black images

[gregvfx]

Hi,

on the farm only one node is rendering black images with correct alpha.
I think it is the denoiser replacing RGB that is producing the black image.
All other nodes work fine, they have similar config.

I can't find back the environment variable (searched on the forum but no luck...) to force the denoiser on cpu, I guess it is using the intel integrated gpu right now.
I dont want to change the BB job for all when only one is wrong.

What is the exact V-Ray version that you are using?
This was a known issue with version 3.40.02 and bellow but it should be fixed in 3.40.03 and 3.50.03.
If you are not using the latest official version 3.50.03 please update and let us know if there is any improvement.

There is no environment variable for the denoiser which can be used to set only particular machine to use CPU for denoising, you could enable and disable hardware acceleration only globally.
It is a good idea actually to turn the acceleration off to ensure that the issue is indeed caused by the denoiser and not something else.
