Prepare the game.

Prepare changed road sections as compact GLB chunks with geometry, UVs, normals and bounds ready before delivery. Existing optimized asset packs stay in use. Road geometry and shared textures use the existing asset WebSocket connection and cache. The last complete revision stays active until the entire new revision is ready.

Preparation starts only when you click. Leave this page open to continue the saved batches. Opening the city or game never starts preparation.

Prepare the Solar System & Starship.

Prepare the Solar System, fitted Earth terrain, Moon and launch sites independently of road and city-map preparation. Uses the current optimized planet assets.

Generate the city map.

Prepare game assets first. Map generation reuses the prepared road revision and renders the city image separately.

Generate the exterior of every parcel as a flat, straight-down map. Houses, hotels, yards, vegetation, billboards and roads are included; interiors are excluded. The game keeps its 4K map, with 2K and 1K exports also available. Static posters from published property scenes are included; videos never play during capture. The renderer stays warm between tiles. Unchanged tiles are reused, and property edits rebuild only the tiles touched by the old or new placement. Completed tiles are saved immediately and reused on retries. Reset & rebuild all ignores existing map results and cached tiles. The last complete image stays visible until the rebuild finishes.

Map generation starts only when you click Generate map. This button does not prepare road geometry. The server continues saved batches automatically after you start generation. You can close this page while it runs. Opening City View never starts generation.
