Hi, I realy hope someone could help me out integrating a 3D object with a 2D image.

My scene is imitating a photo with a table on a floor, where I would like the sphere to cast shadow on the table and the floor, without the 3D box (representing the table) to cast shadow on the floor. I have used a matte/shadow material on the box (table) and on the plane (floor).

The problem is that I can't get the table (box) to "block out" some of the shadow from the sphere falling on to the floor, like it would do in the real world.

Have posted images of my scene under:
In the last image I would like the table (box- still with matte/shadow but without cast shadow) to "block out" some of the shadow from the sphere falling on to the floor, whitout the table (box) casting a shadow.

-How can I achieve this?
