Some meshes are crashing my editor on import, it just shuts down and gives a send error and restart screen. I have a pack of meshes i modelled at the same time in the same program. Some of them open others cause a crash everytime i try. These meshes working in UE4 fine in 4.10. I upgraded to 4.14 and started my project over. Now i cant import these meshes. anyone know possibly why?
