 #                 ### Vanilla.cave Info ###                   #
 # ########################################################### #
 #   This file contains all of the default values used by each #
 # preset. Any value that gets removed will default to its     #
 # original counterpart here.                                  #
 # ########################################################### #
 #                 ### Preset Format Info ###                  #
 # ########################################################### #
 #   The format used by these presets is known as Hjson, a     #
 # less picky and more readable counterpart to normal JSON. It #
 # accepts various comment styles, allows trailing commas in   #
 # arrays, does not require commas in objects when elements    #
 # are placed on new lines, and has other features that should #
 # prevent crashes related to syntax errors. You can view      #
 # hjson.org for more info on using it.                        #
 #   These presets have been extended with ".cave" by default  #
 # so as to more clearly indicate their purpose; however,      #
 # ".json" and ".hjson" are also accepted by the mod.          #

 # the preset:                                                 #
 #   * factor: Multiplies a value.                             #
 #   * chance: 0.0-100.0% probability.                         #
 #   * inverseChance: 1 / X chance.                            #

 # ########################################################### #
 #   Noise blocks are also common. Here's an overview of what  #
 # each value does:                                            #
 #    # Used anywhere that only produces values relative to    #
 #    # each (x, z) coordinate. What this will do is either    #
 #    # determine the minimum or maximum height of a block or  #
 #    # determine whether a particular horizontal space is     #
 #    # acceptable for decoration based on a threshold which   #
 #    # is calculated from `scale`.                            #
 #   noise2D {                                                 #
 #      # Limits the range of acceptable values. In a sense,   #
 #      # this effectively increases or decreases the width    #
 #      # of each peak of values generated. In most cases      #
 #      # throughout this mod, changing the scale in a noise   #
 #      # block alters the size of each area that gets         #
 #      # decorated.                                           #
 #     scale: floating point value                             #
 #      # Alters the distance between peaks of values.         #
 #     frequency: floating point value                         #
 #      # The maximum possible value produced by this          #
 #      # generator.                                           #

 #      # generator.                                           #

 #    # Used anywhere that produces values relative to each    #
 #    # (x, y, z) coordinate. What this will do is produce     #
 #    # 3-dimensional clusters of space. Just because one      #
 #    # particular y-coordinate is valid does not imply that   #
 #    # everything below it is also valid, as would be the     #
 #    # case with 2D noise.                                    #
