  3D point to 2D position in 3D layer

  Posted by Ilya Sire on October 23, 2018 at 10:41 am

  Hello all,
  Im trying to pin each corner
  I have a situation to convert Corner Pin position to other 3d layer point (example at edge of other layer)
  please take a look of my sample file here (from motionscript Dan Ebbert example) Using this, will work if the all axis rotation at 0 degrees.
  12827_3dto2dand3dlayer.aep.zip
  how to match position when it rotate X or Y?

  Thanks
  Sire

  Because your layer is 3D, it will get a 3D point using the fromComp() method.
  Corner-pin expects a 2D value and throws away the Z-information, without actually projecting it on to the 2D plan…

  Luckily, there exists the method fromCompToSurface() which solves this.

  target = thisComp.layer("Green");
fromCompToSurface(target.toComp([0,0,0]));
