underfluid is one of the distribution
provided by CoFH World. It distributes features at the
bottom of bodies of certain types of fluid. It does so by randomly picking X and
Z coordinates and placing features below the highest fluid block or column of
fluid blocks at those coordinates, if any.
If there are no fluid blocks at randomly chosen X and Z coordinates, it still
counts towards the value
cluster-count of the feature
When using this distribution type, the feature type
is used by default, and the value
material of feature type
is set to dirt and grass
blocks (and all variations of
these blocks) by default.
When using this distribution type, the following values must be added to the feature entry.
||String / array of strings||-||
The type(s) of fluid below which features may be placed.
Fluid types are referred to by their internally registered
name, such as
||Block ID / array of block IDs||
(Same as default
The type(s) of block that may be replaced with features.
A feature will only be generated at randomly chosen X and Z
coordinates if the type of the highest block below a fluid
at those coordinates is specified here. Otherwise, the
feature is skipped, but still counts towards the value
