Here is an odd one.  So I've started to add stuff to the character scene above, and in this picture, is just the character, and then the character with a plane.  There is a single infinite light pointing at the charater parented to the camera.

As you can see, with the plane, there is a shadow being thrown on the skirt and boots, but this does not make sense, as the light is coming from the same direction as the camera?  I was thinking maybe its a reflection, but when I turn off Cast/Receive shadows for the plane, this goes away.

Any thoughts appreciated. (for now I am unchecking cast shadows)

...and since I am asking questions, one for zgock:  Using the formula for the eye shader (I guess) how do I reduce the size of the white circular reflections?
