Particle Effects.

It's hard for me to take pictures of rain and water droplets on the floor, (so your're going to have to take my word). I've added a rain particle emitter above my scene and it loops so that rain is constantly falling. I've also done the same with the water splashes on the floor. They are not perfectly timed together, but they are quite convincing never the less. other emitters in the scene include the ember/smoke/flame emitter I have on my torches.
