HitFilm's rain creates realistic rainfall. The rain exists in a 3D rain box which can be moved around your scene - you can even move your camera through the rain.
|•||Preview - toggles between textures and preview particles.|
|•||Direction - the rain can be angled to fall in a particular direction.|
