Tried searching this forum but couldn't seem to get my search terms fine-grained enough. I did find the tutorial on how to paint them in Photoshop, but I'd really love to know what settings I should use to make decent teardrops. These are the settings I have so far.

Oh, and a not-so-quick render to show what it looks like so far. I dunno-is this convincing? I'm aware the placement is a bit awkward, but how's the quality of the refraction?

I can't help you with material room settings, but I can direct you to some tear packages:

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi

Thanks. You have a truly impressive array of links in general, from what I've seen. :) I'll go check these out.
