I tried to open the C4D file to take a look, but I received the following warning "This document may have been created with an unauthorized version of Cinema 4D. For more information or to report software piracy, please visit: https://www.maxon.net/piracy"

Just updated both C4D 2025 and Octane to the latest. From my few minutes of testing, it appears much more stable now, and I am not experiencing the lag issues and crashes with material and opengl previews turned on. Well done and thanks for the quick fix!

I'm getting a lot of crashes doing simple tasks (like dropping a material onto an object, or changing IOR).

Hi Ahmet,

1. Looks like there is a limit of 4 Analytic Lights with light beams, is this correct? I know there is a limit to 8 analytic lights for now.

2. It appears that primitive lights are facing the wrong direction on the z axis when using area shape of ...

Hi Ahmet,

I just wanted to jump in and say no one is blaming you for this issue. Obviously this is a Maxon thing since it only started on 2023.2. We are just trying to provide you with what we notice, in this case an issue, to see if you can find a solution. You're right, this work-around is great ...

Can confirm this solved some issues on my end as well. When building a new scene, it looks like post effects gets added by default (even if not using Octanes post effects). If you delete it, it was intermittently re-adding itself to the test file I was working on. It looks like if you delete it ...
