I think one of the things which bugs me most about it is the way it's reflecting. I had reflections turned to 0%, as well as the "turn reflective with angle" down to 0%. I wanted to have a certain degree of transparency of course, but not much-- enough to be able to see that there is in fact a bulb under each glass, but it almost seems as if the reflections are coming from within it. I think I approached the whole thing wrong, really. :) For me, glass is one of the things which seems to have way too many variables, and I haven't really gotten into editing glass materials as much as terrain materials. Anyhow, I'm starting to think that the glass, when finished, out to have some sort of bitmap texture applied to it as well, so I'll be UV mapping the whole thing after I smooth out the glass a little more in Rhino. I think I might just end up re-building the whole thing in the end, since the "bulbs" also are just a little too faceted right now.
