Houdini Tutorial | Creating Realistic Waterfall Simulation (Step-by-Step)

Welcome to our waterfall tutorials. In this set of tutorials, I'll share the process and techniques of this waterfall creation. The project I show you is at 60fps, which is my usual setting in the previous projects. Actually, I've tested the effect at 30 fps and found that the water dynamics at different FPS are

different. So FPS affects the water dynamics, but it's not the main point here. Well, in this set of tutorials, I will talk about the principal factors affecting the dynamics of the waterfall and analyze the characteristics of the waterfall based on the real reference. Also, I will show you how to manually convert particles to mesh and explain

some detailed settings of the white water. Finally, I will share the material rendering and compositing. All of these are the product experience and techniques I accumulated from my work. Hope it will be helpful to you. All right, let's get started in the next video. Before we start creating a waterfall, we need to find some

references. In fact, no matter what we make, references are always essential. They're pretty helpful for us to set a clear goal. Then we need to analyze the characteristics of the reference. I want to make this kind of a waterfall. Let's first analyze the characteristics on the surface of the upstream water. There is some stacked foam in some areas

because of collision or rocket terrain while in some areas there is less foam because the terrain is relatively flat. And also here the water dynamics at the bevel is quite different. We can see different surfaces of terrain generate different water dynamics. Briefly speaking the terrain has a great impact on water dynamics. This is a pretty
