Worldgen Overview

GregTech CE uses JSON configurations to control it's world generation. It's CubicChunks compatible and fully configurable by users who want to make adjustments for their packs.

On first run, GT will copy it's internal worldgen definitions into config/gregtech/worldgen. After that, you are free to change, modify or remove them whatever you like.

Each JSON file describes one worldgen definition. Usually, it's ore vein, oil source, or stone formation. However, you are free to do any world generations with this system.

On first run, GT will also copy its internal dimension definitions into config/gregtech/dimensions.json. This file is used to specify unique dimension names for the Ore Spawning page, and defaults to providing names for all Vanilla dimensions.
