Hello,
I just updated to Cinema 4D 2023.2, so not sure if this is the issue or not.
Cinema - 2023.2
Octane - 2022.1-R6
I have been using the same scene with success and without issues for the past month, and have never ran into this issue. Everything looks fine in the picture viewer, but it fails to save the file and C4D crashes. In the picture viewer, when the crash happens there is the following copy is in the bottom. Displaying Denoised reflection indirect pass 1/2.
I have copied the whole scene to a new file, and did not have success with that either.
Attached is a screen grab of the console and Octane Log, Octane crash report, simplified scene with the same crash on the denoising.
