  Need an expression to keep effect in same place in 3D scene

  Hi,

  Here is what I’m doing: https://www.youtube.com/watch?v=JNPBMR2CIMU&feature=youtu.be

  This is a short test animation.

  What I’m wanting to do is add the ‘magnify’ (or any other effect for that matter) effect to an adjustment layer BEHIND the big blue beaker (or any other beaker, etc in the set) so that when our main character walks behind a beaker, he’s warped or effected by the effect.

  This works great if I’m not moving the camera. Once I move the camera, it doesn’t work as the effect moves with the camera, or appears to.

  Is there any way to FORCE the center of the Magnify effect to stay ON the blue beaker no matter what the camera is doing?

  Thanks,

  Jim

  Try this:

  L = thisComp.layer(“beaker”);
  fromComp(L.toComp(L.anchorPoint))

  Thanks Dan,

  The first time I tried it there, it didn’t work, but I figured out my Adjustment Layer needs to be 2D and NOT 3D and then it works like a charm.

  Thanks again!
