Water Shader from Unitys Shader Graph to Unreals Material Editor

Hey peoples. I found this tutorial about a water shader in Unity and would like to reconstruct it in Unreal 4. I’m interested especially in the projected caustics effect, or how to use the scene depth to align a texture, but I can’t get my brains around it. It would be great if someone has an idea and could push me in the right direction.

Mucho thanks :v:
