Way to offset scale with 3D position?
In a 3D comp with a camera with a particular focal length, is there a good expression or shortcut for telling After Effects to offset a scale operation by shifting the X, Y, and Z position of the layer so that it’s apparent scale and position stay the same?
I’m turning a few 2D comps into 3D and would like to retain the composition of the shots.

Use the following Expression for a layer’s scale property –
cam = thisComp.activeCamera;
distance = length(sub(position, cam.position));
scale * distance / cam.zoom;BTW, I believe that this example was taken from the Adobe site but its link seems to be broken.
