Quote - Here is the water shader I was using in these latest renders. It is for deep water, such as ocean or lake, where we cannot see anything under the water.

This is not a gamma-correcting shader, and so I would only use it in Poser Pro with PPro render GC enabled, as I've done here.

The scale of the Fractal_Sum is going to depend on the scale of your prop. I used the ground plane here at a scale of 4000%. If you use some other prop, or use the same prop at a different scale, you will need to adjust the Fractal_Sum scale parameters accordingly.

The color I chose for Diffuse_Color, and also the value of Diffuse_Value, was chosen to match a typical ocean color. It matches the photo I'm using here. If you look near the horizon, you see real water in the photograph. My ground plane 3D water shader is matching it almost perfectly.

this is you new way for calculating the fresnel effect right? 
is there any site where we can dial in the settings for different materials that ahve fresnel effect?
