I would like to be able to do something similiar to this. I asked Don Tatro how he did this, but I didn't understand his explanation. Here is what he had to say: What I do is take a water-textured cube which has a water-textured, much-flattened wavy terrain fitted to its top surface, and place it right in front of the camera, so that the camera lens looks both over and into the cube. The rippled light on the underwater surfaces is given by shining a no-falloff spotlight textured with a ripple image down from above. That's about all there is to it. Can someone please help me?
