Today, we dive into After Effects and learn how to create some surreal heat waves by using Displacement Maps. We will first create the map After Effects will use to drive the heat waves, then do a few minor tweaks and go over how the Displacement Map works.
Remember, the map we will create will just be a reference for After Effects to use, we do not need to visually see the map so you can hide it without affecting the heat waves. What is red in the map will be distorted to heat waves and whatever is not red will stay normal. Alternatively, you can turn down the opacity of the red particles to adjust the amount of distortion you want.
Hope you enjoy this tutorial and get ready to add some heat to your projects!
