Creating a large scale waterfall never been easier, it came as a request from one my supporters on Patreon and after some testing well I can get away without using any Flip or pyro keeping it as simple as possible.
When it comes to large scale water simulation it's all about balancing the forces, you feel like it's going down in a slowmo fashion.
Also one crucial part is density and how it affects ( gravity / wind turbulence ) ratio, so denser areas will tend to fall faster while misty ones will see some wind turbulence.
