I REALLY like that water texture. Better than stock, IMO.
I've been playing around trying to come up with a superior beach texture. I came up with something that has a nice "shallows" effect, however I'm largely unsatisfied due to the limitations of the textures. It will take a RADICALLY overhauled terrain system to really be able to do a proper beach.
But if anyone's interested:
We need to have a fourth beach texture for the outside corners
