Shadow through objects, how to fix?

Hello Blenderartists,

I got this problem after creating a spotlight on my game character. As you see in the screenshot, the character has 3 shadows on 3 different layers of the shelve. I dont really know how to fix it. Could you please tell me what option of material should i change to deactivate it. By the way, the shadows on the shelve are baked. Thanks alot in advance.

The only cause I would think of would be that the light and the shelves are on different layers/lighting groups (I don’t even know if that actually affects it in the game engine), or that you have shadow-casting disabled for the shelves. Beyond that, I have no idea :\
