  An expression to keep a nested layer oriented

  Posted by Jon Campbell on December 26, 2008 at 7:46 pm

  I’m sure there is a very simple and elegant way to do this, but I am really a novice at expressions.

  I have a layer moving all over the screen, moving through various rotations in z space. I have one piece coming off of the layer which I’d like to always orient towards a null object below the edge of frame.

  How would you do this?

  Thanks

  This orientation expression should handle most conditions:

  L = thisComp.layer(“Null 1”);
  lookAt(fromWorld(L.toWorld(L.transform.anchorPoint)),transform.anchorPoint)
