YnAMP for Civilization VII

Yet (not) Another Maps Pack for Civilization VII.

What this mod adds

YnAMP extends Civ7 with larger map sizes, Earth maps with fixed geography, and custom map scripts built around the current Civ7 MapScript API.

Included content:

• Larger playable map sizes for custom scripts and Earth maps.
• Giant Earth and Greatest Earth maps with true-start support.
• Geographic Unlock for next-age Civilizations on TSL maps.
• Terra Map with Old World/New World civilization split.
• Terra Fractal and Continents Terra generated maps sharing Terra-style option surfaces.
• Custom start-position shuffles for cultural and Terra-style distribution.
• TSL natural wonder placement modes for Earth maps.

Included maps

Active map scripts in the current build:

Map	Type	Main use
Terra (YnAMP)	Generated	Two-landmass Terra-style Voronoi map
Terra Fractal (YnAMP)	Generated	Fractal Terra layout for explicit Old World / New World play
Continents Terra (YnAMP)	Generated	Compatibility clone of the current Terra Fractal behavior
Greatest Earth Map (YnAMP)	Fixed geography / TSL	Compact Earth map with true starts
Giant Earth Map (YnAMP)	Fixed geography / TSL	Large Earth map with true starts
Massive Regional Earth Map (YnAMP)	Fixed geography / TSL	"Colonization", "Old World", "Indo-Pacific" regions with true starts

See MAPS.md for dimensions, options, and map-specific notes.

How to use it

For Earth maps:

For generated maps:

1. Select Terra (YnAMP), Terra Fractal (YnAMP), or Continents Terra (YnAMP).
2. Choose one of the map sizes.
3. Optional: configure Region Tagging Mode and custom start-position options.
4. Terra exposes landmass ratio and spawn distribution options, while Terra Fractal and Continents Terra also expose ocean separation, distant islands, and fractal landmass-count options.

Known limitations

• Civ7 engine doesn't render textures on tiles where x > 128 on larger map sizes.
• Some natural wonder footprint notes are still empirical and need more validation across repeated runs.
