SCUM Game Water

Hi there, couple of days ago I stumbled upon an Unreal game called SCUM and I love it. They have great new features and ideas that they are putting into their game. But what I loved the most is the water. It looks soooo beautiful. I have almost all of the marketplace or community water assets but I am not sure if they are using any of them. I think they made it inhouse. What do you guys think? I guess there are some SCUM devs here in the forums. Maybe they can tell us how they achieved this beautiful water.
