Unreal 4.11.2 crashes when exporting to OBJ with textures

Hi,

I’m trying to export a scene from editor as obj with texture using file>export all but it keeps crashing. Is it a bug or am I doing it wrong?

Unreal 4.11.2

Small/big scene, same result.

Thanks!
T

Anyone? Is there another way to export entire scene out of Unreal with textures?

Thanks,
T
