On the left/right gunner viewpoints in the Me410 you see a pane of glass alongside the fuselage from the outside in, but it's a wavery mirrory reflection instead of just basic glass. You should probably be able to see through this clearly.
Is it possible to disable reflections on this pane of glass (left and right) when you're in the rear gunner positions, perhaps?
This is a shot from the film viewer just to show which pane it is. It doesn't look as bad as in the actual game -- maybe the viewer isn't doing reflections the same way. Normally you get the big blue slowly updating reflection showing the sky and part of the frame of the windows or something.
