There is no shadow with my Directlight,Why?

I’ve turned the “cast shadow” on ,but it still can’s show the shadow.
can anybody tell me ?

Hey ChenJuye -

Some quick questions just to get a frame of reference to begin helping, What type of Directional Light is it, Static, Stationary or Movable? Have you built and applied the built lighting to you level? If you are using BSPs, have you tried to decrease the resolution for lightmap shadows (if static meshes you would do the opposite and go up in resolution)?

Let me know -
