This rig uses multiple multiply surfaces to create a water depth effect, making the water look more realistic.
I decided that rather than just making a tutorial, I'd simply just make it a download, there's two different versions that you'll be able to download. You can use this rig for your animations and projects, but credit to either this post or the video link are r e a l l y appreciated.
