Applying Color by Speed and Lifetime
In this lesson we'll learn how to change the color of the individual particles based on the speed and lifetime. This can be useful for creating embers that change in color and brightness the longer they are "alive". We'll also go over how to fade particles to create a "cleaner" looking particle system that looks much better when the color is fading in and fading out. This prevents particles from popping in and out and creates a smoother look.
