3D Lights problem with ligh reflection over materials

Hello,

I am working to build a photorealistic scene but i am having a difficult time understanding how to set the lights reflection.

Has you can see on that picture i have a spot light outside the room with the cast shadow on, i have a point light over the bed 

But i get almost nothing on the floor with those 2 lights and a lot of really strong shadows.

I know there is a way to tell autocad to reflect the light on the solids so should get something on the floor with those 2 lights.

But how ?

Help would be appreciated very much.

Tx
