Forum:ACOG scope lighting

I know this might seem like a dumb question. Why is it that, whenever I play the level 'Charlie Don't Surf', the sun light doesn't shine into the ACOG scope causing the scope lens to take on a orange hue? And this is when the level starts when your in the helicopter. When I play the level, I have to have my character's back toward the sun in order for the scope lens to take on that orange hue. If you have any ideas as to the problem, then that would be awesome! Obi-Wan Kenobody
