Forest Pack Effects are expressions or small scripts based on JavaScript that run during the scattering process. They allow you to modify the transform properties (Position, Rotation, and Scale) of scattered items based on specific scene conditions or relationships.
If you want scattered items to shrink as they get closer to a specific dummy object in your scene, the expression looks similar to this: forest pack effects
float dist = distance(fpItem.pos, TargetObj.pos); fpItem.scale = min(dist * 0.01, 1.0); Use code with caution.
fpItem.scale : The size multipliers along the X, Y, and Z axes. fpItem.rotation : The orientation values. This public link is valid for 7 days

Create a new parameter of type Node and name it TargetObj . This will represent your helper object (e.g., a Point or Dummy).
