changing opacity based on scale of layer
Hello all,
Another brain buster.
I am scaling a layer from 100 – 120 every so often and rather than animate the opacity I want to use an expression.
When scale is 100 I want the opacity to be at 100, when scale is at 120 I want the opacity to be at 45.
I’m sure there is an fairly simple way to do this.
Any help would be much appreciated.
Thanks!

This should work:
linear(scale[0],100,120,100,45)

This works perfectly!
Why do I start the expression with linear? Just curious to understand how it actually works.
Thanks!

linear() is an easy way to convert one range to another in a linear relationship. There are other interpolation methods available: ease(), easeIn(), and easeOut()–but linear() seemed best suited to your needs.
