I have been experimenting a lot with UE4's material system recently, seeing if I could push my knowledge. I decided on creating a stylized waterfall effect (because any sort of water effect is always really fun to work on) but I wanted to do something unique with it: For Sky Adventure (My current game project - you can read more about it here ) I really wanted to include waterfalls that the player's balloon could fly through, interrupting the flow of the water as it falls.
