Quote - so what's a good water material?  i've tried roughglass, glass , &  laurie's toothpaste gels but none look much like water when i put them on a plane.  i know they can do it in the Plugin-That-Shall-Not-Be-Named......

Well, water is about 1.3 IOR or thereabouts and I'd imagine you'd need a good bit of cauchyb in there. A flat plane isn't going to look all that great, so if you can rough it up just a little bit, that would probably make it better. Try using some of the filters that Luxrender has for the bump channel and see if that works ;o).
