Sorry, I am very confused now. You said you were getting a black viewport - however the viewport looks OK in the above images and you are getting another error. Can you pls clarify what is happening?

I mean all Rhino viewports are dead, only complete black. (You can see it at some of my screenshots.)

I see - sorry for my confusion. This looks like a Rhino or Nvidia graphics card issue. Have you tried turning off rendering for the graphics card responsible for your display? And I suggest checking the Rhino->Rhino Options->View settings to see if there are any setting wrong. In particular, you probably want to turn OFF Use Advanced GPU Lighting.

Hi Paul,

the Advanced GPU lighting was off already. I disabled my display card for rendering now, but the problem is still there.

I found, if the viewports are black, than I can blind draw a box and start a rendering. So, it looks like the Rhino display pipeline is crashed if Octane was enabled during loading a new file.

As a test, try rendering on the other card. Rhino can sometimes use a different card to your display adapter for it's OpenGL processing. It is worth testing.

This definitely sounds like a Rhino or Nvidia driver issue to me. You are the first user to report this issue. May I suggest posting it in the McNeel forums to see what the Rhino devs say.

Thanks

Paul

I will try my luck at the Rhino side. I afraid if I install the latest driver it could work, but the old driver is recommended for Octane. I will see ... .

Thank you Paul.
