Hi jameswearing,

I’ve tried to reproduce this issue using various animations from the animation starter pack but experienced no problem.

In order to help us troubleshoot your issue, please provide your DXDIAG: (Windows Start Button>(search “dxdiag”)>Launch dxdiag>select “Save all information”>attach text file to your post.)

Also if the crash reporter window is present, select “Copy Callstack to the Clipboard,” paste that information in a document and send as well.

And if possible please include the following logs:

the “UE4.log” Located: Engine\Saved\Logs\

…and the “ProjectName.log” Located: ProjectName\Saved\Logs\

Thanks
