I am going to be making a back yard pool scene. I would like to make the water in the pool as realistic as possible using nodes. In the scene I want to make the water as calm as possible without any major ripples. If anyone knows of any good nodes setups I would love to see the setup. I’ll be using cycles for the final render.
Fresnel mixing glossy (bottom) with either transparency or refraction (top). Gives you better control than just glass. In addition I would do another mix shader after that controlled by lightpath/isShadowRay with stuff already mentioned in top slot and a transparency shader in the bottom slot. The transparency shader can be controlled with a caustics texture map for darkening and brightening, but this could easily become horribly advanced. I would try the volume absorption, if it appears to matter within reasonable densities (depends on the scene), I would keep it.
