Trouble with lighting source "Sun"

Hello everyone, I’m try ing to make my first game and came across a problem with lighting. The “Sun” is acting wierdly, its onl lighting the top surface of everything.



Don’t mind the “Spot” lighting, I tryed with and without it and it didin’t make any difference…
Here’s the “Spot” Lighting side.


Same thing is with the floor, Sun only lights up the top, ignoring all sides and bottom.
And heres just with only Spot lighting.


Thank you in advance!

In which direction is the sun pointing ?

Post a link to your blend file so people can check your scene for themselves

Can’t really say in witch direction it’s pointing.
Here’s the .blend file - https://www.mediafire.com/?dmo5kxd0n62rs1y

The sun is pointing straight down along the z axis so it cannot see the sides of the cubes to illuminate them, only the top face


The position of a sun lamp is not important, the only thing that affects the scene is its direction.

Ahh, ok, now I understand. Thanks alot.
