Using any of the common surface materials (e.g. Diffuse Material) on a mesh causes Octane Server to crash.
The resulting error message in the Blender viewport is this: Error in Render-server at address "127.0.0.1". Running Blender from terminal and reproducing the crash gives this message in the console: "Octane: uploading ERROR"
I get crashes using any of the following materials:
- Diffuse
- Glossy
- Specular
- Metal
- Universal
Portal, shadow catcher, toon, and hair materials all seem to work properly.
Mix, Layered, and composite materials work until one of the problematic materials is plugged in, then I get a server crash.
I can get those crashy materials to render if I add them via Octane Node Graph (Render properties -> Octane Server -> Show Octane Node Graph), but the material is removed as soon as anything updates within Blender.
For what it's worth, Octane X from the App Store works just fine on this computer.
