C4D rampant "Incorrect file structure" corruption
-
Hi clerk-finish,
Please check with tech support.

This needs instant attention.Sorry that you experience the trouble. I assume that does not happen with other apps. Otherwise, I would suggest, if that happens, saving the file to a USB drive (for example).
I hope that is fixed quickly.
All the best

@clerk-finish said in C4D rampant "Incorrect file structure" corruption:
My only workaround, if the file is still open in Cinema, is to save a copy to a local drive, then copy that back to the project on the server.
Hi,
I’m experiencing a very similar issue, but on a MacBook. For over a year, everything was working fine, but after updating macOS and installing the new Cinema 4D version, I started having problems with Cinema 4D. Files larger than 100-200 MB randomly get corrupted. Interestingly, a Windows computer on the same network doesn’t have these issues.
Did you find a way to resolve this? Or have you identified whether it’s a macOS, C4D, or server-related issue?

Hi there,
This may or may not be helpful, but the issue seems to have stopped sometime since the last MacOS update... Started a project, forgot to save locally, but haven't had any corrupt file problems (yet). It's a small project, but when this was happening the size or complexity didn't seem to be a determining factor. Based on this I'm guessing macOS is the likely cause. I'm currently on C4D 2025.1.1 and Sequoia 15.2. I will check back if I start having this issue again (I'm having other, unrelated issues, but that's life with C4D, ya?).

@clerk-finish Thanks for responding, I appreciate it! I’m having this issue randomly as well. Sometimes Cinema 4D enters a mode where all files I save get corrupted, then it just stops, only to come back later. It’s super unpredictable. I’ve updated macOS to the latest version, so I’m not sure if that’s part of the problem, but it’s definitely frustrating.

Hi there,
If there is a problem, please always check with tech support.
It needs to be centralized (at tech support) so solutions are based on all problems. By opening a ticket, the developers get all the data in the best way, organized by tech support. Thanks for considering.
Please check with tech support.
https://www.maxon.net/en/support-centerThank you very much.

@Dr-Sassi Thanks for the suggestion. I’ve already contacted support, but unfortunately, they weren’t able to help. In my experience, they usually can’t (or won’t) assist if the issue involves anything outside of Cinema 4D itself, like server setups or macOS-related factors. That’s why I wanted to reach out here to see if anyone else has found a workaround.

Thank you very much, salt-summer,
Your feedback is welcome, written with just the facts as you see it. Thanks for keeping it on that professional level. I'm grateful for it in many ways.
I have been in situations like that, where the problem is perhaps caused by several "sources," and it is difficult to tell where one's own contribution to the problem starts. You, as the one using the software, should not even be bothered by such things. For that, I say sorry.
However, sorries have very little problem-solving power, and I'm aware of that.
I will try to file a report with the data I got here in the thread. I hope Apple and Maxon can get something done here; the connections between the two companies are typically good.
Thank you, and fingers crossed, this will soon be a story of the past.
My best wishes.

I checked with tech support when this was first happening- results were inconclusive (running through possibilities like including the type of drives we are using in our servers), and at the time they said nobody else was reporting this.

Hi clerk-finish,
Thank you very much for this additional information. Also, thank you for your neutral reporting and sharing information; I highly appreciate the professionalism!
Please know that I have started to explore what happened and the current state of understanding of the source of that problem.
I'm currently not clear if that is connected as well to the preview image problems some artists have mentioned.Thanks for your patience with this. Yes, that needs to be cleared and fixed.
My best wishes!

@Dr-Sassi Thank you so much for your kind and understanding response. I really appreciate the time and effort you’ve taken to address this, as well as the level of support you’ve provided. Unfortunately, during my last interaction with support, I wasn’t able to create a proper log report because of how intermittent the issue is. At that time, everything seemed to be working fine, and I assumed the problem had resolved itself.

Thank you very much, salt-summer.
That is the worst problem: something hard to reproduce, adding another layer of complexity.
Since everyone is worldwide, the one I needed to answer is 8 hours ahead of my time (Pacific Time), meaning he is out of the office already. Sorry about that.
I hope to get something useful to share.
Any product is only as good as its support, which is my personal "credo". I hope my little push will help. Fingers crossed.
Thanks again!
