I'm assuming you have "Trace Refractions" on and have set a refraction value
for the glass you want. If not, that should help. Also, I believe if you want
a glass with liquid in it you should model the liquid separately with its own
refraction, etc. If you want to really get intense with it, it might help to
consider that the glass may not in reality be very homogeneous, and might
want to model some layers with different refractions, etc.
