UE4 won't import smoothing groups!?

Hi everybody, I 've got this strange problem with UE4. As you can see, my smoothing groups don’t appear like the ones in maya, even though I’ve checked smoothing groups on maya export settings.
I also tried to recomputer normals in UE4, but still got the problem.

Do you know what it can be?

Thank you :slight_smile:


I re-imported the fbx file on maya and re-smoothed normals.
I think there was something wrong with my scene in maya, cause I used to work on mac and then moved on windows.
