No shadows

Hi, I’m new in UE4 and I am doing some tutorials to learn the engine.
My problem is that I cant see any shadow with the directional light in the editor, no shadows in meshes and
bsp walls.
Do you know what I am doing wrong?

Thanx in advance.

anybody knows it?

At the begining the shadows work, but when I move the directional light the shadows disappear.

The issue was the quality settings (quick settings)-> put them to epic
