I don't understand what's happening here. If I use the default "Glass Clear RT" texture it renders with a milky-white cast.
Upping the transmission value in the 'transparency' shader from the default 95% to 99% seems to make it more white and less transparent.
Reducing that value seems to make it more transparent, as in you can see more of what's behind, but it's darkened.
I just want some glass that is nearly completely transparent!
What's going on? I've attached the VW file.
