Creating an Animation Remapping Function with Expressions

In this tutorial, we'll show how to build an expression that remaps a complex animation to a simple completion slider. We'll then go on to show how to build the expression into a robust and reusable function that you can use on any property, and call like other After Effects native functions (toWorld or wiggle, for example).

The tutorial is intended for intermediate to advanced After Effects users, specifically those who are already using simple expressions on a regular basis, and are looking for ways to take this further.
