Shading issues when exporting from Blender to Unreal

I’m exporting I model I made from blender into Unreal but I’m coming across several problems. One is the turret appears to have shading seems in Unreal, when it looks fine in Blender. Some parts of the model are also not getting smoothed shaded in Unreal, but they are in Blender.

Dumb question, but it looks like you didn’t apply modifiers in the export?..

I think so. Blender is suppose to apply modifiers upon fbx export.
