So, Miss Nancy, I checked this EasyShader3, and it sure looks good. However, I'm after a slightly different thing. The EasyShader uses a number of different images as a base and is limited to specific figures, because it basically manipulates their texture maps.

 

My shader instead is meant as a universal shader for any kinds of figures or objects, it therefore uses not a single image reference, is solely built from Poser nodes, a real material shader. You can put it on figure X or Y, and if you want can also put it on her shower cap, or a bikini, or the bathtub itself. Any such shadered object is covered with the foam, as long as it is above the indicated water level (which I currently enter manually in the foam shader in centimeters, but I could imagine writing a little Python script entering the water surface height in any foam shader in the scene).

 

Your statement 'p-node is camera specific' is wrong. p-node is related to poser universe (regardless of your camera position), it is working very well, as long as the WATER SURFACE is horizontal (which it usually is in nature ;-)) However I might later even try to create little waves with nodes, and copy this finction to the foam shader so it respects the wave. Do you think this is useful?
