  vertical scale tied to z position of 2ed object

  Posted by Philip Rachford on May 1, 2009 at 4:25 pm

  Hello there,
  I am trying to create an animated 3d bar chart. I have created a 3d box that I would like to scale along the y axis according to the z position of a null object or maybe a slider control. I am not well versed in expressions and suspect that this is pretty simple, but I can’t get just the y scale of my 4 sides tied to the z position of the null. If someone could help with this I would be very grateful. I am using CS3.
  Thank you
  Phil Rachford

  Could be as simple as this:

  L = thisComp.layer(“Null 1”);
  [value[0],L.transform.position[2],value[2]]
