So that's a core problem. Maybe about environments.
We'll look for that. Can you try a different way as clipping to small parts.

With c4d I can do a render at 11000px no problem, but from 12000px there is bug inside image or crash. Very strange....

Yes i tested at different sizes. This is a core issue i suppose. Need to be reported to Otoy guys.

As i can see you're using linear buffer so it has no vignetting. You can render it with a tiling script as 8k. I remember that was mentioned somewhere.

Disable post-processing. Here it works, but post-processing takes a long time to calculate due to the image size and the large number of glare rays. At a resolution of 16K x 16K the post-buffers use 2.5GB on the device, and making the film buffer available on the device for tone mapping / post effects requires that 4x 1GB of memory are page-locked and mapped into device memory. All things together probably run into some limitation or time out.

In a nutshell: If you've got insane render sizes, don't use post-processing.

We are working on moving the whole tone mapping and post processing pipeline to the host (CPU), but until then the size for which you can apply post effects is limited.

After much testing, I have the impression that 11Kpx is the limit for c4d with or without post production. From 12Kpx there are aberrations and splits rendering ...
