Effector: change copies in a region

An Effector moves, turns, scales or fades copies by how close they are to a region.

Try this

  1. Press play. In Demo 4 the copies grow as they pass through a round region.
  2. Select a shape, open Modifiers, click Effector, and switch Falloff between Linear, Radial and Noise.
  3. On Radial, drag Center and Radius. Under Offsets, change At full strength; the + adds another.
  4. Set Invert to Strongest outside to turn the region inside out.
