This script moves/nudges all Transform keyframes in all layers in all comps to the nearest exact frame for any framerate.

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.

jLensBlur is an AfterEffects preset for blurring layers based on their distance from a point.

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

Once you run the animation assistant for Exponential Scale, the keyframes are locked down and if you need to change the start or end values, you have to delete all the intermediate keframes and re-run the animation assistant. Here is a way to replicate the Exponential Scale via expression.
