  Linking scale and rotation to one slider control

  Posted by Paul Connors on December 5, 2011 at 6:57 pm

  Hello Expressioneers! ,

  I’m trying to develop one Slider expression that will accomplish two purposes:

  1) Effect the Y-Rotation of a null controlling a camera
  2) Effect the X-scale of two separate comps.

  I’m creating a 3D room environment with an image at its center. I want to be able to use the slider layer to control the rotation and, as the camera rotates, to control the X-scale of a particular comp. As the camera rotates to the right I want to be able to shrink the X-Scale of the wall on the right so that it does not block the camera as it passes by. I am looking to do the same for the left side wall as well. As the camera rotates left, I want to be able to shrink the X-Scale of the left wall.

  Any ideas?

  -Thanks,
  Paul
