[osg-users] Problem with Shadow Map

I have added a shadow scene (using shadow map technique) to my scene graph and the shadow texture I am getting does not seem to make much sense see:

I turned on the debug HUD, the scene has 3 cars, on top of a white rectangle, and a smaller black rectangle above the 3 cars. The light source is above everything. I do have a shaders attached, and in this rendering I do not have the shadow texture being rendered (with a bad shadow texture the shadows do not come out right).

I have my graph setup as pretty much as:
Composite Viewer-> Scene Root (sky box is attached here) -> Shadow Scene -> Regular Scene (basically everything else). 

I pretty much set the light, and set the texture size to 4096 x 4096, that is about it in terms of what I have set for the shadow map object.

Any advice on were to begin to figure this issue out would be greatly appreciated.
