THANK YOU! This has been resolved in the latest update 2018.1.2

HI aoktar,

I've removed all the plugins and it is still happening. I have reverted back to 2018.1 now, everything works so far and this bug doesn't happen.

New files from clean run without plugins attached.

Thanks!

p.s. A massive thank you from my whole team for working so hard to make this ...

Sorry, I thought I'd forgotten something...

Files attached. Thanks!

Cinema 4D crashes when attempting to create new Octane Material after the Octane Live Viewer window has been closed ...

Eagerly waiting for this since it was first mentioned!

Run a small business and always looking for new solutions, I'd Love to help squeeze out all the bugs before release.

Can test on many different systems too.
