I had this problem once... I don't remeber if I solved it or if I just
'forgot' the project!
Let's see... You can try to control your displacement keeping it with very
small texture amplitude (yes, lots of trial and error, I know)
You can make two liquid objects. One of then is just the top surface (I'm sure
you don't want ripples inside the liquid :) ), so, when you apply the
displacement to the top object and since it doesn't expand to the sides, you
shouldn't have any problems there. But there may exist problems if you see the
glass in a side view, because the objects can separate from each other.
Well, if you just want to see the glass from above, then you don't even need
to displace anything! You just have to assign two surfaces to your liquid
object: one for the top and one for the rest of it. Make both surfaces the
same, but in the top one add some bump maps with velocity over the ZZ and some
high specularity with high glossiness and 'voila', moving liquid on a glass.
No problems with 'liquids that penetrates in solid objects' :)
HEY!!! Thanks to you I solved my problem with the fountain I am making
(wich doesn't look very good at all)!!! Gee, thanks :)
