Quote from MinosSigma: They are pretty simple actually. I'm not stressing myself too much on how "physically correct" they are, but instead I'm focusing on getting them to look "right" (which doesn't necessarily mean "accurate" if you get what I mean).

That's something i've been wondering for a while if physically correct is even desirable for some stylized settings because i always remember that back when movies were made with practical effects they used lard and hairspray and whatnot to make surfaces more shiny. For them it was important that the edges pop on film not that it looks like real life.
