The POOL!

Hi guys!
Here is my attempt at pool water. I fake IOR in a brutal way, but it kinda works
Enjoy

very nice

same using 2 custommaterial, 1 to make refraction on pool texture and 1 to make water turbulences.
code from : http://glsl.heroku.com/e#10585.0

The shader is not complete because I didn't add light and specular, so to fake them I use others material superposed with transparence. but it can give an idea of use of custommaterial

and another just for fun with a strange liquid over the surface :p

Very cool! The only thing that looks unnatural is the strange UV projection on the inner sides of the pool.
I think this can be cured by making the sides separate meshes.

[ikam]

this can be resolved by selecting this faces and transforming uv with transformEx

Ahhh. It replaces Texture transform matrix for such cases. Thanks.
