i think glass would have "ambient 0"

for reflection, i think it would be a variable reflection. My reason is that
if you look straight at the glass, you can see pretty much straight through
it (depending on the type of glass i guess) and if you look at it at a
shallow angle it is more reflective. This effect is very pronounces with
water anyway. glass too i think. i'm not sure of the physical values, but
something like "reflection {0.1, 0.5 fresnel on}"

fade stuff... hopefully someone else can help you on that :) I would have
left it at defaults. I've only ever really used them for lights. i've used
fade_color for murky water once...

good luck!
