You should only see the slight reflection effects, but other than that it should appear relatively transparent. I have experienced what you are experiencing on a different add-on aircraft from a different company. It looked like I was wearing a very dark pair on sunglasses, at night.

Well, in Cap Sim B757 there is indeed a difference between what you see outside the VC and the 2D cocpits.-
I think the windows shouldnt be "relatively transparent", they should be as transparent as in the 2D windows cocpit.-
I dont think I am the only who notices that.-
