  Need to change result values, 82-100 to be 0-400, simple math isn’t enough

  Posted by Kris Alvarado on April 15, 2015 at 9:53 pm

  Ah I am dying, I’ve been looking all day and my eye are about to fall out. Any help and I would really appreciate it.

  I want to make it when I scale up a precomp it’s linked to a matching drop shadow. Fake 3D basically

  So my precomp scales from 82-100 and my drop shadow needs to go from 0-400.
  I added transform.scale[0] in the drop shadow size, so now it goes from 82-100. I’ve racked my brain multiply and dividing with -81*100 but nothing works, I need to go form 0 or maybe 1.

  oh please help, I’m a total noob and at your mercy!

  transform.scale[0]-81*100

  Try this:

  s = transform.scale[0];
  linear(s,82,100,0,400)
