Hello, I am facing the same issue of UE crashing while rebooting when using an alembic geometry cache in the level.
I get the same error saying that ‘The file is most likely corrupt’
Any help would be appreciated.

Thanks in advance!

@Adrien @

Do either of you have a test asset that can reliably reproduce this issue that you can provide? If so I can test on my end and report if I’m seeing the same crash.

I didn’t find anything in our system that would indicate this issue was reported already.

Thanks!

Tim

Thanks for replying, for the time being I was able to get the file in question, which contains about 30 tracks into 3 smaller cache files with 10 tracks each…this way UE loads them up correctly on reboot. Would have been great if we could have the larger file working correctly.
I can send you the file only by Tuesday since i am travelling at the moment.

Thanks again !

Very sorry for the dealy…,Here is a link to the file I was talking about. I’ve been using UE version 4.14.0.

Hi ,

Thanks for posting back! I was able to get the crash and submitted a ticket here: Unreal Engine Issues and Bug Tracker (UE-39946)

Hopefully, we can get this resolved soon!
