The buildings come baked and are placed as instances, so you don't edit them one by one. You shape the city with Rings, Seed, Zone Mix (the share of downtown, mid-rise, low-rise, suburb and industrial) and Uniqueness. The same seed always gives the same cit

Yes. Every car is simulated over your frame range. Cars keep their lanes, turn, queue and stop at red lights, and the traffic lights change on the same timing. Playback, scrubbing and rendering are exact on every frame, and changing the frame range or frame rate updates the traffic automatically.

Rings goes up to 12, which is 25 × 25 blocks. Buildings are instanced, so each copy costs next to nothing. Turn on LOD and far buildings switch to lighter meshes, then to boxes painted with pictures of themselves, and trees become billboards. Everything follows the scene camera, so the render gets full detail where the camera looks.
