  Link Scale to Z Position

  Posted by Tim Montiq on October 7, 2008 at 4:44 pm

  //Start Expression.
  ZPos = thisComp.layer("Null 1").scale[0];
  minScale = 20; //minimum value for scale
  maxScale = 100; //maximum value for scale
  NewZPosMin = 0; //minimum value for ZPos
  NewZPosMax = 500; //minimum value for ZPos
  linear(ZPos,minScale,maxScale,newZPosmin,NewZPosMax)
  //End Expression 

  Is there an expression that will let me link [x,y,z] of a 3D Camera to [x,y,scale] of a 2D layer? I’ve tried the expression below but I am receiving an expected error on line 2.

  Improper planning on your part doesn’t necessarily constitute and emergency on my part

  More like this, I think:

  ZPos = thisComp.layer(“Null 1”).scale[0];
  minScale = 20; //minimum value for scale
  maxScale = 100; //maximum value for scale
  NewZPosMin = 0; //minimum value for ZPos
  NewZPosMax = 500; //minimum value for ZPos
  NewZPos = linear(ZPos,minScale,maxScale,NewZPosMin,NewZPosMax);
  [value[0],value[1],NewZPos]
