  Camera X and Y position matches Null X and Y position?

  Posted by Tim West on September 11, 2009 at 11:44 am

  Hi,

  I’m trying to build a composition in which a camera’s X and Y coordinates correspond with the X and Y coordinates of a null object – e.g. a camera & target set up similar to the target camera in C4D.

  Can anyone help me with these expressions (or is there a better way to achieve this?)

  Thanks,

  Tim

  UPDATE:

  I’ve managed to create exactly what I need EXCEPT one thing ….

  I have my 3D Null layer’s (‘control’) position controlling the anchor point of my 3D content layer (‘Map’).
  However – I only want the Null layers X and Y (not Z) values to be mirrored by the content layer (so the content layer’s Z position remains at 0 at all times.

  Can anyone show me how to specifically target position X, Y or Z values of 3D layers?

  Thanks for your time,

  T

  thisComp.layer("control").transform.position

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