I work on Unreal Engine 4.10.0
This is a school project so I have yet to request my school to update the engine to the latest 4.10.2
I was working on some basic animation in a Matinee Actor just before the crash, in which I have many other animation including some that was imported from Maya. Everything was fine at that point of time.
When I was trying to build the scene, an error saying my system is low on memory appeared. It suggested me to close off Unreal Engine but I proceeded to close other applications on my computer and clicked Cancel instead.
The build finished off much quicker than expected. And immediately after, I tried to open up the same Matinee, and it crashed.
Things I have tried:
- Rebuilding the scene and reopening
- Other matinee actors can be opened without any issues
- Duplicating the matinee actor and opening it
- Deleting some of the actors associated with the most recent
animation I was working on - Reopening the project in another
computer with the same engine version - Deleting the ‘saved’ folder and rebuilding the scene, then opening the Matinee
The project submission deadline is very soon. I hope someone could offer some help. Thank you for your time and patience!
This is the crash report
