Has anybody developed a method for doing photoreal rain that is not too hard on the number of verts in a scene. I have though of two methods, vector particles and indivdual animated drops that would then be dupliverted. I am running low on verts in the scene that I am working on, so I am looking for a low-poly solution of some sort.
I will start hacking away at the issue myself soon, but I just wanted to see if anybody has established a method. It must be resonably photoreal during animation and still.
