Sharp edges in blender cause normal problems in ue editor

I have exported the awp viewmodel from csgo for an unreal movie and while in blender those screw edges are marked as sharp, in ue they create those weird shading shapes. I feel like those should be smooth. What can i possibly do to fix this?

here are the images

What does this topology look like? Hard to give you advice without knowing what’s under the hood here.

My guess is that there’s an underlying issue here with the edge flow of the model and that you’d see these edges in blender as well if you looked closely using the car-paint matcap.

Try dsplce option in modelling mode (deforming tab)
