Having the same issue today - changed the DNS settings, also used a VPN, tried installing different versions of Octane, updating the Maxon App, installing all updates to drivers and system, and its still happening...

If we remove the Octane folder from the Plugins folder for C4d, it stops happening ...

Did you ever find a solution for this, as I am experiencing the same thing currently!

The problem still happens even when I add more AOVs.

Having the exact same problem as the OP - any AOVs are showing black in the Picture Viewer but correct in the Live Viewer.

Any help would be greatly appreciated!

Hey Ron,

We were experiencing the same issue, but managed to get it to work on large files, at least without denoiser - go into your Devices tab in Octane setting and uncheck all of the 'Use for denoising' boxes for each of your GPUs and it should now work.

We are still experiencing the crashes ...

We are also experiencing this issue and are using 4.01.1-R2 on C4D.
Every time you open Octane settings it has reverted back to PRIORITY_HIGH even without closing C4D.
Any way to stop this would be appreciated.

Another update - ive been using it all day and it crashed twice on me - both times when I was trying to use an internet browser at the same time as it was rendering a sequence - I could then repeat the crash by basically trying to use another app like a web browser or mail, while it renders.
