This script allows you to distribute the selected layers in 3D space. In addition to offset position, you can offset rotation/scale/opacity and adds some randomness. The "Factor" parameter allows non-linear offset between layers.

This script creates a 3D pyramid with user-defined layers. Assign a layer to each side of the pyramid, and the script will position, rotate, scale and mask them to build a pyramid of given size.

This script arranges the selected layers in a cylinder. The cylinder is represented by a column of 3D concentric circles (slices) having the same radius.

This script creates a 3D box with user-defined layers. Assign a layer to each side, and the script will position and scale them to build a box of given size.

A nice 'little' free plug-in to create perfect reflections not only in 3D space from videocopilot.net

Chris Kelley will show you how to nest cameras inside Adobe After Effects and update them automatically using expressions.

If you want to use the speed/velocity of a layer's movement to drive an effect ...

This script sequences the selected layers from the current composition time, by offsetting their inpoint.

These expressions save so much time, you might get home earlier tonight just by reading this.

This script can be used to quickly turn layered artwork into a 3D multiplane scene.
