How to achieve an on screen snow clean effect ?
Hi all, I am building a mobile game in which some snow is thrown to the screen by a virtual character. I would like to allow my user to clean the screen by touching it. How can I achieve that ? The snow is thrown via ParticleSystem but I think that it is not possible to clear the particles right where the user touched the screen. An other thought is to make a texture as a sprite and make user paints to alpha where it touches but I don't really know how to do that.
Also I found this shader that looks great http://wacki.me/blog/2017/01/dynamic-snow-sand-shader-for-unity/ but I don't know how to make my scene appears behind the cleaned up snow surplus.
Maybe someone could give me some hint
