About Open Terrain Generator (OTG)

From SpigotMC

OTG is an advanced, fully customizable world generator

What is OTG?

OTG is an advanced, fully customizable world generator. Through its various configuration files it gives the user control over almost every aspect of Minecraft's terrain and structure generation, allowing you to generate anything from floating islands to cave worlds with no knowledge of Java required. OTG supports both Spigot (servers) and Forge (servers and singleplayer).

The basic features of OTG:

Control horizontal and vertical noise, terrain height and volatility
Create new biomes and control the size of biomes, islands and continents
Import custom trees and other objects (BO2 and BO3)
Control over mob spawning rules and climate settings per biome
Generate large custom structures with custom mobs and loot
Options for vanilla structures like mineshafts, strongholds and villages
Full control of all blocks placed during world generation: ores, plants, dungeons, ponds and many more
Customizable options for caves & canyons
Visual settings like custom foliage, water and sky colors (OTG client required)
Generating biome maps from images
Forge Multi-dimension support (create your own dimension and travel to it via a portal!)

What kind of worlds can I create?
