I'm looking for a glass texture that you can't see though, if that make sense? There are some window models that give the illusion of glass yet you can't see through any of them. I'm not sure how to recreate that in a more believable context for windows like the one in this example. Any help or a solution to my problem would be greatly appreciated! I have a lot of windows on this map which I want to keep without ruining gameplay and causing high fps, due to the visibility! Thanks!
