Custom



Customized was a world type that replaced the normal varied terrain of the Overworld with custom features. Because it was removed as of 18w06a, it was then replaced by a new, easy-to-customize but considerably more limited world type called Buffet. Despite being removed, however, Minecraft developer Erik Broes has stated that Customized world types will be returning at some point in the future, albeit "completely different from before" and with "no more screens of 50 vague sliders".

Basic settings
There were 18 customization options which affect whether structures will generate, among other environmental factors.

Ore settings
Each of the eleven sections of this page modifies the generation settings for each type of ore. These settings can be used to change the distribution of almost all any ore and mineral type. The only exception is emerald ore, as it only generates in extreme hills biomes, and the vein size is always one block; as its distribution is hard coded, it cannot be changed. The distribution of natural resources in the Nether (gravel, soulsand, Nether quartz ore and glowstone) also cannot be changed.

Apart from the above exceptions, the vein size, number and distribution are set. Here are the default settings:

 * A world with tall, expansive caves that have numerous springs. They are so porous that parts of the caves are sunlit and have vegetation. Caves often have wacky structures that hang from the ceiling. Sometimes, they have expanses of water near the floor, despite the low sea level. Floating islands are a common sight, but they are less frequent than in Isle Land or Amplified worlds.

 * Lava oceans=Yes


 * A predominantly stone and gravel world with lava oceans, dry rivers, and little or no vegetation and animals.

Trivia

 * The customized world type is based on a Minecraft mod Ryan Holtz made in 2012 called Wedge.
 * The following preset can be used to generate a world similar to the Amplified world type:

 * If the Far Lands are re-enabled using mods, increasing the "Coordinate Scale" will cause them to generate much closer to the origin.
