Check out some of the textures from hl2, you should be able to find out from there how to do it.

Or steal some.

I read a very interesting article *somewhere* where it was explained how valve created all the liquid textures in portal 2. It had to do with a lot of stuff, like realistic flow around objects. But I cannot seem to find it.

The main thing with water textures is that they have a so-called flowmap. This is an RGB- colored image that actually tells the liquid where it has to flow.
They have a normalmap, to make it look more fancy.
So creating a custom water texture is a very very complicated process, much harder then creating a normal texture

So if you want an ocean-like texture I'd go for ChickenMobile's suggestion: Just steal one from HL2

Were you thinking of these slides?

Ok, I recently made a few textures for my map and I was wondering, how do I make a water texture?

I want the water to be sorta blueish w/ foam, like an ocean, but I don't know how to make it act like water! plz help!

There are some good textures that you can use for Portal2 (even though they were originally created by the author for CS) and also a good tuto making some textures (these ones are waterfall textures... also available and running good in Portal2!). I hope that you can learn some!
