Hello -

I am not finding your crash logs in out system, can you first make sure that you are submitting the crash log when it comes up in the Crash Reporter? Also, it would be helpful to see the FBX which is causing this crash, can you either attach it here or link to a place to download it?

Thank You

Hi -

I was finally able to track down the same callstack from another user. It is a known issue and reported as UE-20756. It also looks to have been fixed in 4.10. If you would like you can test your asset in 4.10 Preview 4 to confirm.

Thank You

I just upgraded to Maya 2016 and started having this issue. I switched the FBX export version back to “2014/2015” and everything was fixed! :smiley:
