David iz cool,
Are you using DarkBasic Classic or Professional? On the contrary, there might not be a standard setting for glass. But, the amount of fade on an object needed to be glass, would depend on how transparent the glass should be.
Take your object you wish to be glass, use
GHOST OBJECT ON Objectnumber to make it semi-transparent. Then, simply fade it out some amount, using
FADE OBJECT Objectnumber, Fadevalue. Experiment with the value until you get the desired fade.
As an added effect, duplicate this same object and place it at the same location as its first. Scale the duplicate up a tiny sum, and then texture it with a fitting reflection image texture. When the camera rotates, have its texture scroll around it. This will create a nice "fake" real-time reflection on the glass window.
