I get the installer scene from Unity, clikc Load Octane in the PBR Settings window and get those two errors:

I'm running Unity 2018.2.12f1, Octane version is 1.1.1.1341 Windows 10, with CUDA 10/ cuDNN
My guess is that it can't find the cuDNN, because I have CUDA 10 installed and the path is c:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.0\bin\ not *\v9.0\bin
But ... before I start messing with installing earlier CUDA versions, what's the confirmed, working combination of Unity, Octane and CUDA/cuDNN ? The CUDA_PATH in the System Variable already points to the right folder, so maybe there's some other issue?
