Try throwing this expression on a 3D layer's scale pro= perty with a camera in your scene named "Camera 1"

camZ =3D thisComp.layer("Camera 1").position[2] * -1;

layerZ =3D position[2];

scaler =3D (1/(camZ / layerZ)) * 100= + 100;

[scaler, scaler, scaler]

When you move the layer around in Z, it'll scale to appear the same = size from the camera's point of view. =A0Then create another camera tha= t you animate -- when the second camera matches position with the original = camera, all your objects will line up.

I made this a long time ago, but if I recall correctly,= it may be off if you use a camera that isn't 50mm, but it should get y= ou started at least! =A0There's probably a more elegant way to do this = that Dan Ebberts has already figured out. =A0;)

I=92ve been eyeballing i= t but that has to be an easier way or some math I can do.

Thanks,
