This usally happens when normals are facing the wrong side of the mesh
enter image description here
Using the backface culling in the N panel will make the concerned faces transparent (see-through as in your UE4 game engine)
enter image description here
You can check your faces normals with this option in the N panel. This will show you the normals in the viewport.
enter image description here

To make the normals consistent go in Edit Mode with Tab, select all with A (only the bad faces could be enough), and use Ctrl+N (recalculate), or Shift+Ctrl+N (recalculate the other direction), or select the faces and click Flip directions
