Minecraft CityGen builds cities from structures you mark up inside your own Minecraft world, using a handful of marker blocks.
For buildings, place:
- a Gold block and a Diamond block at two opposite corners of each region you want captured.
- an Emerald block horizontally adjacent to the bottom gold block to mark the authored ground level.
One gold/diamond pair creates a one-piece building. Three vertically aligned pairs with the same footprint create a stackable building with bottom, middle, and top pieces. Placement type is independent from layer count: type-1 controls repeatable city buildings, type-2 controls unique landmarks, and either type can be authored as a one-piece or three-piece asset. A sign above the emerald can set stack options.
You can tune any three-piece building with a sign directive above its emerald: stack: 3-7 — how many middle sections it may grow (min–max)
The exact rules for roads and buildings are in the in-world asset conventions.
