I don't understand that you mean by "how I can create rain coming down in the water in the image", but here is a rain tutorial that might help. http://www.geocities.com/SiliconValley/Program/3093/tutor/bryce/rain.html I did a pic with a lady standing in the rain. There is a rain texture in Bryce 3D, all you have to do is create a volume figure and make it big enough to cover the camera veiw, then apply the rain texture to it. You can see what I mean here. http://www.geocities.com/Paris/Palais/7193/water.jpg I hope this helps.
