Creating smart workflows for repetitive tasks is an important endeavor while working. Especially in After Effects where you can be easily faces with a mountain of repetitive tasks quickly. Dylan Winter shows a process for using the Layer Indexes for Expressions in After Effects to easily automate tasks that you may need to do more than once.
In this tutorial I propose two plausible uses for the layer index property when working with expressions
In these examples, Dylan shows how to create images that animate in a specific way in After Effects, showing how you are able to automate the process using After Effects Layer Indexes With Expressions showing a workflow for using TimeRemap for keeping a clean composition structure for your project in After Effects, and another example where he uses the After Effects Layer Indexes with valueAtTime to create a animated cascade effect on any layer attribute.
