Hi,

I tried my best over days. Can't figure out how to get the eGPU workin in choosable in the preferences.

Hi,
firstly, to check that everything is working correctly, please download and install Standalone OctaneX from App Store.

Then open Standalone, right click anywhere in the node graph panel, and choose Materials/Metallic, to create the material node.
Now right click on the node and choose Render.
If you see the Material Ball scene rendering, everything is working correctly.

I'm not a Blender user, but you should need to go to preferences/add-ons, and check that OctaneX is selected as render engine.
Then go to the Scene attributes, and change the render engine to OctaneX.

ciao Beppe

Hi Martin, it sounds like the scene itself is probably fine since the final render works correctly. I’d check the Octane viewport settings, GPU selection, and whether both 1070 Ti cards are being detected properly. The black interactive window could also be related to the specific R20/Octane version or driver combination.
