I am in the exact same situation as meuliano (I just want a water surface, and perhaps subtraction volumes, but no physics or underwater), and I’m also completely new to Unreal Engine.
I can’t complain, since is one of the few free things for Unreal Engine, and it looks very high quality, but it’s very unfortunate that it’s not prepared for blueprints, forward rendering and VR.
Hopefully some day, someone will update it for that purpose! Now I must go shopping for something that works.
