Creating a polygon that blocks/affects light sources

I'm working on a little test with toon renders and i've noticed that lighting will affect each object independently. That is to say, Placing a plane or other polygon between the light source and my landscape does not create a shadow or block the light.

I'm working towards a sort of stained glass effect, where i place a translucent object with a moving texture between the light source and object to create the effect of clouds passing under the sun, but baby steps, y'know?

Hi,
If I understand right, your objects don't cast shadows?
What type of light source do you use? Try it out with spot light or with the "Sun and Sky" preset in mental ray.
You may check the attributes for the lights under shadows and make sure
"Use Deep Map Shadows" or "Ray Trace Shadows" should be ticked.
Also you have to check under attributes for the shapes, here you have to make sure under Render Stats, that "Cast Shadows" is ticked.

Regards and Merry Christmas!
