Why, exactly, do you want to have a giant glass dome in your map?
Well it's still pretty terrible, but I guess it means I have a proof of concept. Now I just have to make the textures and models not a steaming pile of poo.
It looks a bit better in game, because the reflections actually move. A solid color for the glass with low opacity and a very soft normal map seems to be the best bet, the one in the screenshot is a bit over exaggerated.
Phong ended up being a bust, it doesn't do what I thought it did. I went with a standard envmap reflection.
It strikes me as a little bit odd to have wooden shacks in a futuristic dome. It seems to me like it would make more sense to have retro futuristic buildings, what they thought back then that the future would look like.
Not sure if I have already posted this but this is for a trade map (death match)
