What is the After Effects Proximity Animation Effect?

📌 What is Proximity-based Animation?

"Proximity response" means that the closer a layer is to a reference point (usually a null controller), the stronger the animation effect is triggered; the farther the distance is, the weaker the effect is, or even none at all.

It simulates concepts such as magnetic fields, gravitational attraction, and light decay in the physical world, making the picture more dynamic, interactive, and spatially layered.

This design that triggers changes based on distance is called:
