  Trigger scale with markers

  Posted by Jonathan Reyes on March 10, 2024 at 12:37 am

  I have a few (a lot) cubes that need to scale up and down at specific times. Multiple time on some.

  I want to be able to just move a In marker and Out marker.

  The Error says dimensions need to be two.

  I found this expression that work on Opacity…

  var In = thisLayer.marker.key(1).time;

  var Out = thisLayer.marker.key(2).time;

  var dur = 0.2;

  linear(time, In-dur, In, 0, 100);

  linear(time, Out, Out + dur, 100, 0);

   

  Can someone help

  Try it this way:

  In = thisLayer.marker.key(1).time;
  Out = thisLayer.marker.key(2).time;
  dur = 0.2;
  s = time < (In +Out)/2 ? linear(time, In-dur, In, 0, 100) : linear(time, Out, Out + dur, 100, 0);
  [s,s]
