How create a cool swimmable Water? Just like Ue3

I create a prototype of swimmable water seeing this tutorial : Unreal Engine 4 Tutorial - Quick Swimmable Water - YouTube

i have no sucess…

The first problem is the third Person Template…I can’t swim up…and the my other problem is when you reach the bottom of the Physics volume you lost the “water simulation” and start to walk…

I my test i reach on a Brush inside of the Physics Volume…and when I start to walk…I lost the gravity underwater! Here is my render!

If you don’t use C++ you can right click your CharacterBlueprint>PropertyMatrix Then go to Pawn>and check Use Controller Rotation Pitch.
