An amazing game, an amazing effect

An amazing game, with an amazing effect

 
Some months ago i put my hands on an amazing game called Rain. It's an adventure game in which the player takes up the role as a young unamed boy who is invisible and can only be seen when standing in the pouring rain. The game is impressive! It has a sensitive atmosphere and an immersive story. But, as a developer, what really caught my attention, was the partial visibility/invisibility of the character when only part of him was under the rain, and part was under some cover. This effect can be seen a lot in the video below.

Mimicking the effect

I liked this effect so much, that i had to figure out how to implement it, just for the fun of it.
So I spent this saturday morning playing with some shaders and cameras and achieved a very close effect. You can see the result in the video below, or you can try it yourself here.




With some particles and a "wet surface" shader this could get even closer to the original. Not bad for a quick try huh ?
