Very cool tutorial, I think I can need that 
EDIT: So basically it just pans the texture in a given direction… Wouldn’t it be more realistic to have some deforming and distortion effects? As if the water surface would be in motion? (Although Iam not sure about how to achieve that at the moment)
How does your setup look in real time?
EDIT2: Or is the Motion_4wayChaos dealing with that already?
