Hi guys.

I use rendering a lot to communicate and advertise certain proposed products to internal customers. We also specialize in packaging. For the attached packaging shape, we have two thin plastic inserts that fit inside a thin plastic shell. Essentially, there's thin plastic inside thin plastic. While trying to render this though, you'll see that it gets hazy as the light goes through the other plastics. As I know this packaging technique is used in current manufacturing and packaging, I know it should be clear. What settings should I be tweaking to make this much more realistic? Think headphone packaging or action figure packaging.
