FBX meshes problems

[Digital Shamans]

I have this kind of issue in 90% of cases. Do you know what causes it, what should I do before exporting mesh? OBJ is fine, only FBX has this problem, regardless of exporting settings I almost sure.

What 3d app are you exporting from?

Thanks for interest.

Other issue which might be related is that i see new seams on a model in main viewport (but not in unwrap editor), after importing fbx mesh back.
Easy fix for the issue visible on screenshot is to import mesh back and export again.
