Glow to expression slider

[Lord Scales]

I could not get it so good, but try creating a Null Object (Layer > New > Null Object – we will call it Controller -) with a Slider (Effect > Expression Controls > Slider Control). So copy and paste the following expression in Glow Radius:

freq = 2; //frequency of wiggle
amp = 15; // amplitude of the wiggle
slider = thisComp.layer(“Controller”).effect(“Slider Control”)(“Slider”); // creates a variable to catch the value of the slider
maxRad = 25; // the maximum radius you want the glow to have
minRad = 0.5; // minimum radius
seedRandom (3, true)
w = wiggle (freq, amp); // creates a variable to catch the wiggle value

linear (slider, 0, 100, minRad, maxRad) + w // as the value of “slider” changes from 0 to 100, the Glow Radius will change from mixRad to maxRad value and this value will be add to “w”‘s value

Now the Glow Radius will wiggle but the main value is going to be controlled by the Slider in the Null.
If you prefer a simple expression just try this:

freq = 2; // frequency of wiggle
amp = 25 // amplitude of wiggle
wiggle (freq, amp)

It works like the bigger one, but the main value will we controlled by the Glow Radius itself.

I tested the both here and worked fine.
