I am working on something that is proving to be a challenge, and hope you all could offer some insight.
I've got a scene with a beach, and the tide rolling in and out. So what I want is for the sand to change colour, but only when the water comes in contact, then after it rolls away for the colour to gradually fade back to the original, and so on and so forth.
I remember doing something like this years ago, but can't remember how and like a fool of a tooke I never wrote it down.
Any help at all would be appreciated, and naturally any progress I make will be posted here as well.
wet maps. XParticles, Effex, Blackstar's Little Happy Paint Shader, probably vertex maps if you are good enough with xpresso, possibly Proximal with the right gradient or invisible objects trailing....
