Is this light behind the polygon?

Then the normal of the polygon would be facing away, so it would be dark.

I think...

For example:
the light is attach with the fps camera.
a cube is near the camera, a wall is further.
so, the cub should be brighter than the wall.
but, in irrlicht, the further corner of the cube is very dark, darker than the wall which is far away!
I know, the further corner of the cube is a vertex, which has faces that the light can't reach, be, the face that is lighted shouldn't have so dark a corner, which is darker than the wall far away.

and , that corner vertex has three normals because it relate with three faces of a cube.
