  lookAt and parenting

  Posted by Jan Sickinger on March 5, 2011 at 10:55 am

  hello forum.

  i’m working on a little after effects character rig. to rig the eyes, i used a 3d lookAt expression. so i rigged the iris layer to the HELPER_Iris layer. all objects are 3d layers. that works all fine, except i parent the HELPER_Iris layer to the higher HELPER_ALL layer. when i do so, the Iris layer flips around and do not work properly anymore.

  has anyone an idea to this problem? thanks very much!

  LookAt = "HELPER_Iris"
look = look_at(position, thisComp.layer("HELPER_Iris").position);
[look[0], look[1], look[2]]

  Try it this way:

  L = thisComp.layer(“HELPER_Iris”);
  lookAt(L.toWorld(L.anchorPoint),toWorld(anchorPoint));
