Alright! We finally got an in-house repro!! Whew! I've been chasing this ghost in the machine for quite awhile! It looks like the "Mogrt is Corrupt" issue occurs when the Motion Graphics Templates Media scratch disk is set to a folder that is nested so many levels deep or in folders with really long names that goes beyond the 260 character limit that file paths on Windows machines are limited to by default. The .aegraphic files within a Mogrt gets unpacked in the Motion Graphics Templates Media folder inside of folders with a Unique ID that also has a really long string of characters. It throws Windows over the edge to where it doesn't recognize the file path as valid.
We are looking into a workaround on our end but in the meantime, I found this article that shows where you can go in Win 10 to change this limitation. https://mspoweruser.com/ntfs-260-character-windows-10/
You can also open Project Settings and change the Motion Graphics Template Media Scratch Disk to a new location with fewer nested folders or closer to the root.
I have not been able to reproduce this issue on a Mac though. It looks to be specific to Windows. But if you are experiencing this issue on Mac please reach out 🙂
Hope this is helpful!
