Hi Florian,
Thank you for your reply.
If possible, please project files; images are very limited in information and more of an additional help. Over the past two decades, it has shown clearly whether a file works (except the problem is outside of the file, e.g., hardware problems…)
Project files as ".c4d" can be uploaded directly (below 1MB, and images with a height of max 500 pixels)
My best wishes
