Shadows not working properly!

Hey, i’m having a problem with lighting the room I recently modelled.
Shadows are working fine everywhere except for the floor, and I don’t know how to fix it, help? :smiley:

The image is attached.


Argh i’ve made another pointless post, I fixed it, I must of accidently added a material stopping the shadows, :frowning:

Sorry about the spam post.

You REALLY could provide us with more infos about your scene…since we don’t know about your current lighting setup, we can’t help you.
So, do you use Raytracing, which kind of lamps, where are they located, etc.
