Animating the scale of a motion path [solved!]

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?


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


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");

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

As always, Mr. Ebberts is the KING!
