Finally, here's a breakdown of the technique I used to create the water in my old 'Tropical Diorama' UE project. It got a few improvements since then :) Hope you'll find the video useful! Files are available as a Tier 1 reward on my Patreon: https://www.patreon.com/GhislainGir

A simple water sea shader i made. Not a to complex shader but can still use a bit of optemization, Packing all textures into one would already optemize a lot. The water texture is really simple, just some quick deformed cells noise
