OTOY Forums

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.

OS: MacOS Big Sur 11.2.3
Graphics: AMD Radeon Pro 5500M 8GB
RAM: 32GB
Blender Octane X version: 22.2 PR11 (2021-04-21 10:18)
Octane Server version: 22.2 PR11 (2021-04-21)

I have the same problem

A fixed version was put on the downloads page about an hour ago.

Unfortunately it looks like they had to roll back some features like scatter on surface and scatter in volume. Hopefully those will be back soon.

Hi,
please try to completely disable the Intel GPU, also for Tonemap, if present, and render only with AMD GPU.
