Coverage fans draw on the ground plane in real meters — the mounted box's long axis equals the car length. Toggle groups, then pick a sensor to tune its zone. FX layers target the fans with full generative control.

Shapes (F tool): click the plane to place, drag moves, Alt-click or Del deletes; reach/spread/fade define the region. Renderers stack on top and draw through every shape. Flow streams: the first shape is the source (its reach = stream length), the rest deflect — neg attracts instead. Link web ignores neg shapes.
Path (T tool): click to lay control points; click a point to select, drag moves, Alt-click or Del deletes. New clicks insert after the selected point. Widths, dashes and spacings are meters on the road.

Segment mask
