In City Sample, all the streetlights, vehicle lights and lit windows at night use emissive lighting and there are no analytical (point, spot, area) lights - maybe that’s what you are thinking of? When you have as many lights as City Sample the performance cost for hundreds of shadowed analytical lights becomes very high and having enough emissive light sources gives Lumen enough light to work with so you see less noise and “wobbling”. You may want to look at City Sample if you are going to have a ton of these street lamps and can’t afford analytical lights. In most cases for larger light sources like street lamps an analytical light is preferred until the performance cost becomes too high.
