Octane 2021.1.6 for Unreal Engine 0.59 - Unreal 5.1 *Updated Tweet

[ChrisHekman]

Does it always crash on 5.1? Or specific scenes? I could not find the crash you are talking about.

Metahumans are not fully supported at the moment, and various materials might end up black.

crashes every single time, regardless of the scene

Once I click on the Render in the render target

What is your hardware situation? Windows version, GPUs?

Win 10, RTX 3090[/quote]

Thanks, ill try them.
That being said, ive uploaded a new version of the 0.59 plugin that works with the latest version of UE5.1, could you check if it still crashes?

Also crashing on Existing & New projects with 0.59 build on UE5.1
Octane didnt work on the preview 2 build either.

Edit: Same build 0.59 loads without crashing with UE 5.0.3

Seems like a problem with SM6 and DX12. Loaded SM5 + DX11 on UE5.1 without same crash on Octane load.

Even with the new update, instant crash when Octane is loaded.

This build fixed a hard crash that i think is the underlying cause of your crash.
