For now I’m more into waves and I left the shore aside. The technique I use is very similar to ( and a bit inspired by) this : Crashing Wave Rig
It’s part of a commercial project so I won’t be able to share stuff until it’s released, but I hope I would be allowed to share some breakdown since it’s quite complex and it’s hard to find a lot of examples of stylized water.
