  3D Corner Pin to corners of another layer

  Posted by Dan Fredley on July 29, 2010 at 5:02 pm

  I am trying to connect two corner pin points to the upper right and lower right corners of another 3D layer using the 3D corner pin expression on motionscript.com, but I’m trying to convert the anchorPoint part to the upper right corner on the target layer:

  Can anyone tell me what I am doing wrong?

  Thanks.

  target=thisComp.layer("UL");
fromComp(target.toComp([target.anchorPoint[0]+target.width/2,target.anchorPoint[1]+target.height/2,target.anchorPoint[3]])

  Try this:

  target=thisComp.layer(“UL”);
  fromComp(target.toComp([target.width,0,0]))

  That worked perfectly of course–thanks Dan. I also modified it to figure out the lower right corner of the target layer(for any of those interested):

  target=thisComp.layer("UL");
fromComp(target.toComp([target.width,target.height,0]))

  It worked until I tried to move the target layers in z-space–the expression no longer keeps the corner pin to the target layer. I tried different values in the z property to no avail.

  Nevermind–the corner pin layer was accidentally set to be a 3D layer. Once I turned it to 2D it worked again.
