I've tested it in both C4D V2023 and C4D V2024 using Octane 2023.1-[R1], Octane 2023.1-[R2] and the older Octane 2022.1.1-[R4] - it's all the same thing.

I'm using X-particles in the scene as well, but completely removing this makes no difference. It still crashes instantly, taking C4D down with it.

Also, on a side note, for this same project but in a different project file I've noticed that camera motion blur if the camera is following a spline using the "align to spline" tag is completely messed up, I really can't explain what is happening other than everything becomes one big blurry mess. EDIT: This seems to only happen if the spline being used for the "align to spline" tag is generated using the tracer object.

Well as I said, even completely deleting the particles from the scene still results in a crash on my end, only when I enable motion blur in the camera tag.



this is the message that I'm getting, clicking OK just closes C4D entirely.

I've also attached the bugreport that C4D saved

I think I've figured out the cause of the crash. The camera is currently being animated using a couple of GSG+ Signal tags (For handheld -like motion) these tags were on the camera itself, moving these tags away from the camera on onto a parent null seems to prevent the crash, even with the snow particles present in the scene.

If you don't know, GSG Signal animates parameters without keyframes, I think Cinema 4D sees it as an expression, so maybe this is a bug with expressions controlling the camera + motion blur?

Quick question regarding a possible bug with the post fog; When I change the resolution to do a final high quality render, the fog does not scale with the resolution and thus changes in appearance. This is also visible when using the live viewer. Is this a bug or am I missing a setting? I thought the scale with film checkbox would help but I don't see a difference. Is it possible to link these values, so the resolution does not make a difference?
