Dude what are your glass settings? Also do you have anything in the environment overide slot in Vray?

In THE ENVIROMENT map a gradiant map, when i use a bitmap it's the same effect
glas material simple vray map,reflection settings to midgray and refraction almost to white other settings or not changed.
