  Proximity script 3D issue…..

  Posted by James Michaels on October 1, 2015 at 1:52 pm

  Been over to the old JJ Gifford site to use the proximity script he made.

  My comp has a vertically scrolling menu of individual text layers. These move up and down over a highlight area (a null called PROXIMITY). Once in that area they scale upwards (as well as an adjustment of opacity). They move up and down using a single keyframed null.

  Currently use this set up:

  // Scale with control layer
  // Applied to Scale parameter

  // Point1 is current layer, point2 is control layer
  point1=this_layer.toComp([0,0,0]);
  point2=this_comp.layer(“PROXIMITY”).position;

  // Find the vector between the 2 points
  delta=sub(point1, point2);

  // Now find the length
  distance=length(delta);

  //Remap distance to large scale when near, small when far
  ease(distance, 0, 67, [100,100], [69,69]);

  All working great. But I need the text layers to be 3D as this comp needs to continuously rasterize in 3d space within other comps. As soon as I turn the layers to 3D the expression dies.

  I tried amending the final line to the following with no joy:

  ease(distance, 0, 67, [100,100,100], [69,69,69]);

  I just get no scaling at all. My PROXIMITY null is also a 3D layer.

  Any ideas?

  // Scale with control layer
// Applied to Scale parameter

  // Point1 is current layer, point2 is control layer
  point1=this_layer.toComp([0,0,0]);
  point2=this_comp.layer("PROXIMITY").position;

  // Find the vector between the 2 points
  delta=sub(point1, point2);

  // Now find the length
  distance=length(delta);

  //Remap distance to large scale when near, small when far
ease(distance, 0, 67, [100,100], [69,69]);
