  Animating the scale of a motion path [solved!]

  Posted by Brian Nishii on December 9, 2017 at 12:11 am

  I have a flare parented to a null that is moving along a motion path.
  Is there anyway to animate the scale of the motion path while the flare is moving along the said path?

  I know you can copy/paste motion motion path to shape path and scale, but to animate it?

  [EDIT]

  In case anyone stumbles onto this, I found an elegant solution to what I wanted to do using Dan’s space transformations here:

  So,

  1) “TargetNull” follows a motion path inside a PreComp.
  2) PreComp is resting in a MasterComp with collapse transformations.
  3) “FollowNull” will follow the TargetNull with these expressions in position parameter:

  L1 = comp(“PreComp”).layer(“TargetNull”);
  P1 = L1.toWorld(L1.anchorPoint);
  L2 = thisComp.layer(“PreComp”);
  L2.toWorld(P1);

  Now, I can scale the PreComp inside the MasterComp, and my FollowNull will follow nicely!!

  As always, Mr. Ebberts is the KING!
