I'm encountering an error when trying to render in 3ds Max 2018, saying "mismatched OptiX version, found 6.1.0. expected 6.0.0.". How can I fix it?

Hi

That's a warning, and you can safely ignore it. GPU rendering should still work.

Newer NVidia drivers have a newer version of Opti. This newer version of Optix is compatible.

We'll be removing this warning in newer versions of Arnold GPU

@Stephen Blair In my case rendering was stopped after this warning. There is "Rendering..." and after it the rendering screen remains black without continuing.

I'm rendering and I get the same warning.

Can you set the verbosity to Info and get an Arnold log?

Hey, @Stephen Blair. I've set the verbosity to Info and here is my log.txt. I still do't understand where is the problem with my rendering.log.txt
