Octane constantly crashes after hitting render on the live viewer and stays stuck at 'Export Material'.

No bug report and no pop-up crash box, I have to force close C4D each time.

I've tried multiple Octane versions from 2020 to the experimental 2021 versions and multiple of the latest Studio and Game Ready drivers.

What about a c4doctanelog.txt?

Please, open the scene, then go to c4doctane Settings/Log Output tab, and enable all the Log option checkboxes.
Then, load the scene in Live View, then in Picture Viewer, or until crash, then reopen c4d, navigate to c4doctane Settings/Log Output tab, press the Generate log report button, and share the resulting octanelog_report.zip file, thanks.

You may have some material content which causes crashes if you are using multithreading for materials. Disable "multi-threading for materials" option and try again.

Thanks for the quick response. Attached are two log reports, 1 where I try with Live viewer and it freezes and the another when I try and render to Picture viewer and it crashes with a pop-up.

I've tried with it ticked on and off, same result.

Then you have to do some optimizations. Try to delete some of materials until find the reason.

These are pretty simple scenes with simple materials there's no reason why they should be crashing the render. I've tried with all materials removed and it still crashes.

Did you find anything from looking at the logs..?

Hi MindofImpact,
please upgrade c4doctane to v2020.2.5-R3, and report back.
You can find it by visiting your personal Downloads area:

I Upgraded, worked for a little while then started crashing again. It seems like once it starts affecting a scene that scene won't work again until I transfer the entire scene to a new C4D document.

Attached bug report. This is seriously holding me back now.
