Arnold Optix Denoiser Error

Anonymous — Wed, 06 Mar 2019 11:49:53 GMT

Hi! I've tried Arnold renderer for the first time. It worked fine until I turn on Optix denoiser, I got this error

// Error: no compatible NVML version detected for use with OptiX //

I also noticed that my graphic card doesn't show in GPU for Optix section (render setting), but it show in the output window when I open Maya. Not sure it is the cause or not. I searched on Google and this forum, but couldn't find solution. Have anyone experienced this issue before? and How to get rid of this error? Thank you in advanced.

I've attached a screenshot of the output window. I'm using Maya 2019, Windows 10 Home, with NVIDIA GeForce GTX 1060 with Max-Q Design.

What's the version of the GPU driver?

Can you open a command prompt and run C:\Program Files\NVIDIA Corporation\NVSMI\nvidia-smi.exe ?

Thank you for asking Stephen. Just solved it today with help of the support
team. The cause is Arnold looks for nvml.dll in C:\Program Files\NVDIA
Corporation\NVSMI. Not sure why I don't have this folder, so I created the
folder and copied nvml.dll from System32 and pasted it in. That fixed the
error.

Error: incompatible NVML 5.326000 detected, version 6.343000 or higher is required for OptiX.

I'm not sure about 3dsmax. In my case, I created NVSMI directory in C:\Program Files\NVDIA
Corporation and I copied nvml.dll from Windows\System32 and pasted it into the folder. Hope that work for you too.

Hi. I have the same problem. It seems that I will not able to figure it out. I have RTX 2060, latest (461,92) Nvidia drivers. Maya 2020.4 and arnold MtsA 4.2.1 and Arnold Core 6.2.0.1.

But can not see anything about "optiX denoiser" option in the arnold settings at the AOVs tab. Actually it is writing at the system tab as "error" under the Device Selection/Render Device Fallback line.

Any help appreciated.
