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.   Screenshots: Video Showcase: Downloads: Current version: (1.2)
