Rain in Unreal Engine

I have spend all weekend reworking my rain system for one of my project and I will be using this in my new game to give it a more cyberpunk feel. It is more advanced than your typical rain systems because it automatically detects what faces are upwards facing and creates splashes on the surface, drips from the sides and it also leaves the bottom look dry for if your using it for like a shelter for the player but they can also see the top and sides of it as well.

As this rain is also a part of my fully dynamic weather system, it allows for multiple weather such as rain and snow. It also has a day / night cycle. This system that I have made is very powerful.

Thinking about this more, If I make this year's game with this and virtual reality, it would be pretty awesome because it adds to the cyberpunk theme.

Reflecting on its current state my next approach to improve this would be to dynamically create clouds based on a mask created with noise that is added to the skysphere that get darker depending if it is raining. Another good idea for this is to add more complex weather conditions such as thunderstorms, wind, etc...
