How to fix Octane showing black screen?

[seaissi]

Hello,

Sorry, I am not sure how to use the correct format here...
My octane is showing a black screen and the Log shows:

Compute error 2097152:814:
compute device 0: Linking 00696900aaaadec4 shader failed
device 0: failed to initialize render thread 0x7fdc09784250


And in the Console window it shows:

Does this mean I don't have enough RAM? or some file is missing in my computer? How can I fix this problem?
Thank you!

Hi,
which exact model of GPU do you have in your Mac?

Unfortunately old AMD GPUs and Intel GPUs are not supported anymore in new OctaneX PR12/13 for macOS 12 Monterey - there were some Apple Metal driver related issues.

Only AMD Vega, Navi, Big Navi GPUs, or Apple Silicon M1, are supported in macOS 12 Monterey.

ciao,
Beppe

Anyone else have a black screen when using VNC to see a Windows 10 render node?dinosaur game

Try to use TeamViewer, or Splashtop Streamer, instead of VNC.
Splashtop Streamer is free till 5x machines.

ciao,

Is there a more specific way?

Hi,
have a look at Splashtop Personal, it is free, doesn't have any issue with CUDA:

And it is super easy to use:

Ever get weird errors in Cinema 4D that seem to come from nowhere? I had a FumeFX error once, and it turned out a plugin needed updating. Did the trick!

I ran into something similar a while back, and in my case it turned out not to be Octane itself but a mix of GPU/driver compatibility and plugins. A couple of things you might want to check:
GPU support on macOS Monterey+: As Beppe mentioned, OctaneX PR12/13 dropped support for older AMD/Intel GPUs. If you’re on macOS 12 and not running Vega/Navi/Big Navi or Apple Silicon, it will just fail to initialize (black screen every time).
FumeFX / plugin errors: I noticed in your log it throws a FumeFX library initialisation error!. I once had the same type of error in Cinema 4D, and the fix was just updating the plugin—black screen went away after that.
Remote connections: If you’re testing over VNC, you might also hit black screens because of CUDA/Metal display issues. Switching to TeamViewer or Splashtop solved it for me.
If none of that helps, double-check the GPU/driver + OctaneX version combo. The render device log line you posted (failed to initialize render thread 0x7fdc09784250) is almost always a driver/GPU mismatch.

Yeah, I'm seeing the same issue. I'm trying to figure out a solution right now.

This looks more like a GPU compatibility issue than a lack of RAM. The log shows OctaneX PR13 running on macOS Monterey, and older Intel or AMD GPUs may not be supported by this version. I’d first check the exact GPU model against OctaneX’s compatibility requirements, then verify the Cinema 4D and OctaneX versions match. The missing updates-ox.txt file and FumeFX error may be separate issues, so I’d investigate GPU support first before reinstalling everything.
