Open Terrain Generator (OTG) Mod 1.16.5/1.12.2/1.10.2 offers a data-driven world generation tool for Forge and Spigot. The new device helps you fully control Minecraft’s world generation.

About Open Terrain Generator and Features
It’s available for you to form entirely custom generators and share them with other characters as your mods. These are OTG presets.
It’s possible for all to make a preset. You can shape anything that you think without having any knowledge of Java.
Main features
Manage horizontal and vertical noise, terrain height, and volatility
Set new biomes and control the size of them, islands, and continents
Design and import custom trees with other items
Build large custom structures. They are mineshafts, strongholds, and villages, cities, mountains, volcanoes… with custom mobs and loot.
And many more
Notes
By default, OTG is packed with a default preset that is identical to vanilla world generation. Please create your own preset or download one that has been made before doing any cool content!
