How to add coastline detection (for smoother transitions between the water and the coast) using blender cycles material nodes?
My intention is to do something like this water shader made for the Martinsh from BA.
But insteed of a real time shader, I wish a blender cycles shader!
I managed to recreate all major aspects... volumetrics, caustics... but I can't find a way to do the smooth transitions between the water and the coastline!
Someone have a hint?
