I rendered an aft view of my starship WIP, and discovered something odd...

If you look at the nacelles in the attatched image, you'll see that they 
apear to be dark... not lit by the same lights as the rest of the ship. 
  Is this caused by my having a spotlight unioned into the nacelle 
definition?

Since nobody came up with an answer, I thought I'd go ahead and record 
what I discovered, just in case someone else has this problem down the road.

The image was rendered with an orthographic camera.  After reading the 
documentation, I was under the impression that most of that was 
controlled by the up and right vectors, as opposed to the location.  (As 
a side note, I still don't completely understand the up and right 
vectors... perhaps someone could spend a little more time on them in the 
next release of the documentation?)

Long story made short, I put the camera inside the length of the 
nacelles, which resulted in me getting a cross-section of them at the 
plane of the camera, which was, naturally, dark, because no light 
penetrates to the interior of the object.

Placing the camera further back gave a nearly identical image, because 
the up and right vectors controlled the size of what was in it, but with 
the full nacelle, which was properly lit.
