StandardGen

The StandardGen algorithm is closely based on the ore generation algorithm used by vanilla minecraft. It has been modified to to support the special features offered by COG but is still fairly limited compared to the Cloud and Veins algorithms. Most players are comfortable with StandardGen, though, and it allows for faithful reproduction of the vanilla distributions when necessary.

StandardGen Algorithm
The StandardGen algorithm spawns roughly elliptical "clusters" in each chunk. The horizontal position of each cluster is random and the vertical position is determined by the Height setting. The Size setting controls (very roughly) how many blocks each cluster contains.

The  element creates a distribution using the StandardGen algorithm. The  element creates a non-generating distribution that can be used as a source of default settings.

Attributes
The StandardGen algorithm may have the following attributes: * These attributes are only meaningful in debugging mode.

Settings
The StandardGen distribution may have the following settings:

Replaces
 elements can be used to change which blocks a StandardGen distribution will replace (the default is just smooth stone).

Biome
 elements can be used to customize which biomes a StandardGen distribution will spawn in (the default is all biomes).

Parents and Nesting
A  element may be placed inside another StandardGen, Veins, or Cloud element. The parent distribution will continue to spawn normally, but the child will only spawn near it's parent. The exact range is determined by the ParentRangeLimit setting.
