Yeah, it was the first game I've ever used an outside lighting source on. It was also the last.
Hah, I remember being halfway done with the game, only to find out that the lighting engine could only render about twenty levels before completely crashing. Hoo boy was that not a good day. Thankfully GearGOD pulled through and updated the engine, though it still has way too many quirks to be reliable. A shame too, since it looked stunning.
