Well, this discussion went a little too deep for me at the time I read it (about 10 mins before my bedtime), but I still managed to come up with a related question: Given that the theme of this thread is "make liquid look more realistic" (and given that we're talking about close-ups here), is there any way to simulate the meniscus? My only idea so far is to use some booleans: one well-flattened sphere (to create the initial curve), grouped with a "negatived" a cylinder (carefully positioned) negatived against the flattened sphere (to create a flat bottom surface), both booleaned negative against the top of the liquid. errm.. I hope that made sense. I'm 2 mins from bed-time, and mind is running liquidly...
