This tutorial covers how to apply expressions to the x and y positions separately in the puppet tool. In the previous tutorial, Wiggle on Position, I showed you how to apply a wiggle position to x and y separately using the Separate Dimensions option. The puppet tool in After Effects doesn’t have this option so we have to use an expression to achieve the same effect.
In this tutorial I’ll show you how to add an After Effects expression that will randomly turn on and off a layer’s opacity to create a blinking effect.
