Generate seeded island and overworld maps with water, sand, grass, forest, mountain, snow, and settlement tiles.
The tool blends seeded value noise at several scales, applies radial edge falloff when enabled, and classifies elevation and moisture into terrain types.
Yes. Keep the same seed and settings to reproduce the same terrain, settlements, and roads.
It lowers elevation toward the map boundaries, encouraging surrounding water and creating island-like continents instead of clipped land.
Settlements favor passable grass or sand cells and keep distance from existing settlements. Roads then connect consecutive settlements with simple routed paths.
The export contains seed, dimensions, settings, terrain legend, a two-dimensional tile ID grid, and settlement coordinates.
