Multiplane expression added manually does not work
I’m using this expression to create a multiplane expression on my comp:
camZoom = 2666.6667; distance = position[2] + camZoom; scale * (distance / camZoom);
When I add it using a script named PSDto3D that I found at motion graphics exchange the expression works fine, however when I revise it to
camZoom = thisComp.layer(“Camera 1”).transform.position[2]*-1;
distance = position[2] + camZoom;
scale * (distance / camZoom);which is basically the same, the objects are displaced also in x and y as soon as I start dragging them in z space. The scale works fine according to the expression but there multiplane effect is not achieved, everything moves in a very obvious way.
Can anybody tell me why the second variation doesn’t work?
Thanks.camZoom = 2666.6667; distance = position[2] + camZoom; scale * (distance / camZoom);camZoom = thisComp.layer("Camera 1").transform.position[2]*-1;
distance = position[2] + camZoom;
scale * (distance / camZoom);

It seems to work fine as long as the layer’s anchor point is on the camera’s z axis. If you have it off-axis, I would think you would need a position expression as well, to keep the layer on the camera’s line of sight that passes through the anchor point.

Thanks Dan.
You mean having the layer’s anchor point “aligned” to the camera’s z axis on its point of interest?

Yes, so the layer’s anchor point will be in the center of the camera’s view.

Thanks a lot again
