Your waterfall really looks pretty good, odeathoflife. For waterfalls, I'd recommend two things to you. First, try the Troubled Water material, if you weren't already doing so. Second, I don't have a copy of Easel, but in its Material Editor, can you adjust the angle of incidence of the reflected light. I get some reasonable results when I make the angle of incidence very low. This tends to make the white part of the reflection occur earlier, and it looks more like white foam that way. I wonder if I can create a "foam" bitmap that we call could use for this. Walks out of room for a little bit.....
