cluster is one of the feature types provided by CoFH
World. It generates somewhat round deposits of blocks. It is often
used for generating ores.
When using this feature type, the following values must be added to the feature type configuration.
||Block ID / array of block IDs||-||The type(s) of block that the deposits consist of. When specified as an array, a block type is selected randomly for each generated block.|
||Number||-||How large the deposits are. This value is not measured in blocks, so some experimenting is needed to obtain the desired result.|
