Field Driver is a distance-based animation tool for Adobe After Effects. It lets layers react to controller layers or a drawn path without requiring manual expression work.
You can use it to drive position, scale, opacity, color, rotation, look-at behavior, time remapping, and even custom effect properties from a single controller setup.
Field Driver calculates how close each selected layer is to a controller, then uses that distance to animate the properties you choose.
