Hi,
I had originally posted this issue in the GPU section assuming it to be driver problem. recommended nvidea driver - General - Chaos Forum
It seems Nvidia AI denoiser has issues in the latest Vray version (Sept 25 release). I installed the previous version (Vray Next for Rhino 5 4.00.02,Apr 23 2019 release) and Nvidia denoiser works without problem.
Love the Nvidia denoiser especially for fast interactive denoising. Could we expect a fix?
Thanks.
B. Maio
