The thing with Cg troopers is that it they are based in the computer and not in real life so reflections etc happen because someone has programmed them to be there. But in real life things are much different. The stormtrooper armour doesn't reflect the muzzle flashes, which are bright, even in dark lighting so the chances of them reflecting the laser fire is small, if any chance at all. The blasters in the OT were REAL firing props, unlike the plastic lightweight crap ones using in the PT. These things actually fired and created a real, on-set muzzle flash. Guess what....no reflection on any part of the armour

So i won't be adding any reflections to the troopers armour
