hey, so I don't know whats going on, but I'm having lighting issues, like with the lip of the stock RX-7. it will just randomly turn into a light gray color instead of its normal black look, I don't know whats going on an I really need help fixing it because it kinda ruins the game for me, it happens on a lot of cars, like the evolution 10's front bumper an allot of its custom parts will have this same issue..does anyone know why this is happening?
