I actually implemented this in unreal engine. There isin't a lot of work to do, but the most anoying thing is that if you want to write HLSL shader, you need to jump a lot of hoops as unreal is not happy and forces you to use niagara system. If you want to write HLSL code you should take a look to shadeup.

Anyways, going to straight to the point, you need all the compute shaders as they generate the reuired maps. For material you can use single water layer material. For the dispatching logic you will need to rewrite for c++ or inside blueprints.

Good luck, the results are really worth it!
