On my MacbookPro, I am running macos Catalina 10.15.6. I downloaded the Octane demo, and it works perfectly.
However, when I run Octane for Blender I receive the error as described here (viewtopic.php?f=25&t=74005). In particular, the errors are: I cannot open the "Device Preferences" in the Octane Render render settings and the rendering is stuck on "Waiting for image".
I installed the Nvidia cuDNN drivers that was prompted in the dialog box.
What might be going on here such that Octane isn't working in Blender?
