I have a cloud of 2D layers spread across 3D space. The front/center layer is the controller. I used this tutorial as an entry point substituting position for scale. What I want instead is for the layers to move relative to the objects around them. Does that make sense? If the object in the top left of the cloud moves toward the center object, all objects between the two shift proportionally. That said, ideally the initial position is set with the layer's position value, not procedurally generated by the expression.
