Unreal Engine 4 Scripting with C++ Cookbook

Leaves and Wind

In this recipe, we'll write a simple particle shader demonstrating how to create leaves in wind. We can do so using a Particle Emitter combined with a Material Shader that "shades" our leaves to give them the appearance of blowing in the wind.

How to do it...

1. Create a new particle emitter by right-clicking in the Content Browser, and choosing Particle System.
2. Construct a new Material shader by right-clicking ...
