What do you mean with "Realtime"? I wanted a realistic water effect with breakers and wave behaviour (a logo rising from the pool). I have been searching for poser stuff, asked Vue d'esprit users, ended up with Lightwave (I used Lightwave some 8 years ago on the Amiga computer, it was first called Silver I believe) and the RealWave plugin. This is a frame of a gallrey page: http://www.nextlimit.com/realwave/gallery/gallery.html Main page: http://www.nextlimit.com/ Extremely realistic wave simulation. Installing is a bit complicated and the tutorials are not cut for LW 7, but it does work like a charm. The bad news is that the plug-in costs some 500 dollars, the good news is that it they offer a demo so you can use it for one project, sell the project and buy the plug-in
