CityWorld ReForged

"You have chosen, or been chosen, to relocate to one of our finest remaining urban centers." — Welcome to City 17

Procedurally generated cities for Minecraft — NeoForge on 1.21.1, 1.21.11, 26.1, 26.2 and 26.3, and MinecraftForge on 1.20.1.

Advanced configuration

• Configuring CityWorld — all ~100 settings, the three ways to set them, and worked recipes. Start here.
  • Villages and other vanilla structures — CityWorld suppresses vanilla structures so it can own the chunk; one small datapack turns them back on.
  • Your other mods' blocks and biomes
• Building Palettes — which blocks build the cities, and how to add your own.
• Commands — including /cwlocate, which is the quickest way to tell whether a datapack change actually took effect.
• Permission Nodes — for servers.

Settings and terrain changes only affect newly generated chunks — existing chunks never regenerate, so a fresh world (or unexplored land) is needed to see worldgen changes.
