I'm evaluating Octane after using Arnold for Cinema 4D (C4DtoA) for the past five years or so (mostly the CPU version on an HP workstation).
I'm experiencing the issue of Cinema 4D locking up when I close the LV window.
I'm on a 2022 Mac Studio with an Apple M1 Ultra with 128 GB of RAM running OS 13.1 Ventura. I have the free trial version of Octane X Prime for Cinema 4D (Ventura version downloaded from here:
https://render.otoy.com/shop/primex.php) installed into a brand new install of Cinema 4D R26.
(I'll note that I'm hopelessly confused by all of the various iterations of Octane out there. Is this free version identical to some paid version? Beats me.)
My initial test scene was working fine, and I was able to repeatedly open and close the LV with no issues. But upon quitting C4D and then reopening the scene I found that closing the LV would produce a spinning beachball, requiring a Force Quit of C4D.
After a bunch of tests and troubleshooting I found I could prevent the LV lockup on existing scenes with this procedure:
Launch C4D and create a new/empty scene
Open the LV (you don't even have to activate a render)
Close the LV
Open the old scene and work normally. Closing the LV will NOT lock up Cinema 4D. It's like the LV has to be "primed" in an empty scene.
Weird. As I note above, I don't know whether a licensed version of Octane would be exhibiting these issues, too. I see that someone on the Cinema 4D plugins forum is having LV issues, too, but I can't post there.
Cheers.
