This is the fun bit. I wanted to know if it would look realistic or not. I think its about half and half. Some aspects about the way the water flows in and out look good but there is no momentum on the water so it doesn't slosh in and withdrawl properly - water would stick around on the flat bits for longer. And if the surf texture could work out where in the past time it was white and stay white surf then it would help too. But I like it near to the rock pools area that bit looks good. I guess where the water is sloshing up some incline of more than 20 degrees then it looks right as it pulls back out under gravity. It would be nice to see this in my 3D viewer but that doesnt handle animated textures and I have no intention of making it so either. It does handle automated loading of the texture so I could do a frame load it in 3D, save the screenie of it and keep doing that in some kind of script but thats a bit of a pain to set up. Also, I havent tested that feature of it for what must be at least 5 years now.

I am definitely going to hang on to this shader definition tho. I can see this coming in handy for a number of other scenes that I could do with water in it.
