And if you want to go really wild I've got a fog and atmosphere tool in my store, soon be here too. It will do a prety good job of fog, rain, snow, volumetric light. Comes with lots of presets to get you off the ground, as it is a bit tricky to get what you want. (Kind of like photographing real fog!) As for waves and ripples, like Scott said, the best poser can do is the wave deformer. Pretty good for simple stuff. [](http://www.nerd3d.com)
