Draws lines from a shape layer to up to ten other layers and keeps them connected however the layers move.
Tutorial, 0:34
Everyone needs an interconnected web of layers eventually. Networker draws lines from the shape layer it sits on to up to ten other layers.
Apply it to an empty shape layer, choose up to ten targets in Effect Controls, then parent the shape layer to the layer you want to network from. The lines follow their targets wherever they go.
To install, drop the .ffx into your After Effects User Presets folder under Shapes, refresh the Effects and Presets list, and it appears under Animation Presets, User Presets, Shapes.
