Thank you David for your answer.
We are using 3ds max 2016 (18,0 SP5 commercial) and Vray-next (update 3.1 (4.30.01 build 00001)
Our operative system is Windows 10 Pro 64bit verison 20H2
As CPU we have Intel® Xeon® CPU E5-2680 0 @ 2.70GHz 2.70 GHz (2 Prozessoren)
And as GPU NVIDIA QUADRO k5000 with driver version 188.8.131.5239
the message that we get from V-ray when rendering in CPU or GPU and using the AI denoiser is:
[VUtils::setDenoisingDeviceContext] No suitable CUDA devices available for denoising. Compute capability >=5.0 is required.
Now that I read the message again I realise it says nothing about optix…sorry for the confusion, I am not sure where did I read that.
When we render with the vray next GPU, we got engine type set to CUDA and under the “Device name” got checked this: *Nvidia CUDA Quadro k5000 GPU index0
Under that it appears the next message when the first render is done: “Succesfully updated the user and the current process env variable VRAY_GPU_PLATFORMS=nvidia cuda quadro k50000 gpu index0; with the device to use”
Also, when starting a render in the vray messages, it says: “Optimized CUDA kernel assembled succesfully”
But when the AI denoiser kicks in, we get the error message from above saying that no CUDA devices are available for denoising.
