Lantios Portrait Lights and Direction Control?

Ippotamus

I'm using the latest 4.5 release.

So I was using exceedingly awesome Portait Lights recently and thought I knew what it was doing.
But it seems I was wrong.

I had a figure.
I had a wall.
I had a shadow.

I wanted the shadow to hit the wall in a certain place, so I went to adjust the lights.
It seems no matter what I moved, the shadow simply did not move.
It was very frustrating, I finally ended up moving the figure and wall. lol

I adjusted the UE2 with all of the Rotate Dials and noticed no change in direction.

Am I missing something with this particular set up?
