In the example I was toggling the y position intensity on and off.

The top of the wall is a bit brighter than the floor and the base of the wall. (The light source was dark red)







Self-Lit

You may have noticed that bottom of the wall was bright blue even though the light source was dark red.

Walls, like most of our objects, have lights and terminals.

These lights and terminals are self-lit, regardless of how dark the room is.
