  Lock 2D position of a 3D layer with a customizable Z

  Posted by Benoit Kergosien on June 14, 2017 at 7:56 pm

  Hi folks,

  I would like to have the possibility to customize the Z position of my layer with my X and Y constrained to their original values.

  In other terms when I modify my Z, the X and Y coordinates are recalculated to mimic their original positions.

  Sounds a job for an expression for layer space transforms but Im a bit stuck with toComp, fromComp…

  Hope someone could help!

  Thanks,

  Benoît.

  For now I can only achieve to parent my 3d layer to a 2D null with the expression:

  ref = thisComp.layer(“2D null”);
  newPosition=ref.toComp([0,0,0]);

  Unfortunately I don’t know what to do next, and if its a good first step btw.

  Benoît.
