A scene holds thirty-two lights at a time, and each model is lit by the eight of them that reach it most, as the consoles of the era lit each thing they drew: a sun always, a lamp when its range touches the box around the model. So a corridor of twenty-four torches is lit all along, each stretch by its own.
The floor and the walls are made of pieces, so each piece takes the torches near it, and they are subdivided, because the light is worked out at the corners. The car is one object with four lights of its own: four calls in it, two headlights and two tail lights, each placed by its own transform, with no useSpawn for each.
