What's new

LostCities 1.20-7.5.0

  • Hierarchical streets:

- Added versioned hierarchical street generation with primary, secondary, and tertiary roads, wider primary roads, slopes, connectors, and deterministic large bridges. Existing worlds keep legacy street generation

- Added an optional city-style tertiaryparts street asset family, defaulting to the secondary-road parts family

- Added a separate openLotParkChance profile option, defaulting to 0.8, so hierarchical open lots use varied park parts more often without changing legacy park frequency

  • Inter-city highways:

- Added a versioned inter-city highway network which creates deterministic routes between likely city regions, with endpoint-based or fixed highway levels. Existing worlds keep legacy highway generation

- Added dedicated highway bend and T-junction parts

- Added highway-side gas stations and two-chunk restaurants with parking lots, automatic highway-facing rotation, matching deck heights, and configurable foundation supports

- Fixed rotated restaurant doors, opened highway railing for restaurant and gas-station access, and added two-high restaurant perimeter railings

  • Buildings and structure avoidance:

- Structure avoidance now treats each multibuilding as a single footprint, so it is either generated completely or avoided completely

- Fixed scattered multibuildings sometimes generating only partially. Their complete placement and validity are now decided once for the entire scattered area

- Fixed bugs in blacklisted-structure checks that could miss structures or fail on structure references without registry keys

  • Performance and stability:

- Improved performance when searching for forced building spawn locations

- Reworked world generation for safe multithreading. Non-overlapping chunks and different dimensions can generate concurrently while nearby chunks and lifecycle cleanup remain protected

  • Assets, tools, and documentation:

- City styles can now override hierarchical open-lot park frequency with profile_overrides.openLotParkChance, independently from legacy park chance

- Added forcedair part metadata for hard-air cells

- The /lostcities debug command now reports the containing multibuilding name

- Added practical profile customization examples and developer documentation for custom assets, city generation, and world-generation thread safety
