Does the OLD LIQUID material method still work?

[tomlai]

Sometimes when there is very thin wall thickness for the glass or plastic container, it gets tricky to try and force the modelling software to create an offset of the liquid into the glass.

Can we use the old method of having separate materials for each interface surface like before> Glass | Liquid, Liquid | Air and Glass | Air
Or has the liquid material behavior been updated ?

I don't see liquid surface like in earlier versions.
