SOTW Light Surprise

OK so I have up to three area lights randomly rotated around the Space Ship. Last night I change the random seed value, havn't done that for a few renders, and suddenly all the light sources are on the far side of Space Ship.

The nearside of is not lit. I realised what had happend about 10 rows into the render and was about to stop it rendering...

... when I had to let the dog out. So I come back and the render is finshed. WOW! Fantstic effect, all of the structures on the Ships surface are back lit with no forward detail shown.

The moral of the story, I guess, is dont stop renders that you can leave. The result might be unexpectedly good.
