title: Shadows going through objects
body: <p>I'm new to Lighting in 3D. Just started working with Unity3D. I was creating a sample for myself to test shadows and there is a problem.</p>

  <p>As you can see that i have created two simple walls with two cubes. Also I have setup a directional light. Let's go the backside of the walls to view the problem

  <p>Technically the front wall should be blocking the shadow of the back wall. But it is not. I have painted a read line to show that where the shadow of front wall is overlapping the shadow of the other, meaning going all the was through the wall. Why is that happening. Help please...</p>
