Hi,
For correct refraction the normals of the glass should point outwards. (I think this should be OK if you export from Sketchup)
The glass material should be set to a specular material with an index of around 1.45. The node inside the last pin gives the properties inside the glass, set the absorption to an RGB spectrum and add some absorption. Set red and blue to slightly more than green, so more green light passes through. Adjust the scale slider until the right amount of light is absorbed. See http://refractivesoftware.com/forum/vie ... =21&t=9380 , look for Medium node parameters for an example of absorption settings.
