Corona Corona for Cinema 4D Help Required

Hi

I have the problem that Corona renders dead pixels. When the image builds up and renders, black pixels are generated! See attached screen-shot.
Can you please help me urgently?

Thanks

Hi there, can you tell us what version of Corona you are using? Are you able to share the scene with us?

Hi, yes sure I would be very happy to share my screen with you in a save setting.
I use Corona 9 hotfix 1 with C4d R25 121 but I never had this problem before. Best Katharina

This is the error warning I get when I start the render process of the Image.

Hi,

Thanks for testing this. If you have any custom render presets, can you please delete them and try again. It may also be a material that is causing this. To test that you can use the material override option in the general render settings with just a default Corona PBR material. It’s hard to say exactly what it might be without having access to the scene. Hopefully, some of these suggestions may help you.
