AE | Expression Driven Gauge - Part 2


In the first post, we looked at building the base and setting up the numbers, now we're gonna make the Master control and get the bar to change colors.

AE | Expression Driven Gauge - Part 1


Expressions!! Expressions can be used to control various properties of a layer but their use if quite situational. It really depends on how you intend to use your composition. This will affect the approach you take as well as whether it's necessary to use an expression at all. I think the best way to illustrate this is to use a real-world example: a gauge!

So, we're going to make a "Core Temp" gauge as in the header above. It's pretty simple, right, but we're mainly going to focus on the decisions we make about the expressions driving the different elements that make up the gauge, and how we're going to set up the entire composition to be 'expression-friendly'.
