Well, you can of course have it anyway you like, it is your project, but I was just thinking out loud, from an ingame point of view.
I'm not keen on dark windows in games, because it's just not that goodlooking when you're actually playing from the wheelhouse/bridge. I prefer no glass at all, because a game just cannot give you clear glass like the real world has. It's always a sort of haze, that you look through, if you know what I mean..
Your picture is dead for me btw....
