### `sheet`
Creates a sheet of ore in a blob shape according to the 2D perlin noise
-described by `noise_params`. The relative height of the sheet can be
-controlled by the same perlin noise as well, by specifying a non-zero
-`scale` parameter in `noise_params`.
+described by `noise_params` and `noise_threshold`. This is essentially an
+improved version of the so-called "stratus" ore seen in some unofficial mods.
-**IMPORTANT**: The noise is not transformed by `offset` or `scale` when comparing
-against the noise threshold, but scale is used to determine relative height.
-The height of the blob is randomly scattered, with a maximum height of `clust_size`.
+This sheet consists of vertical columns of uniform randomly distributed height,
+varying between the inclusive range `column_height_min` and `column_height_max`.
+If `column_height_min` is not specified, this parameter defaults to 1.
+If `column_height_max` is not specified, this parameter defaults to `clust_size`
+for reverse compatibility. New code should prefer `column_height_max`.
-`clust_scarcity` and `clust_num_ores` are ignored.
+The `column_midpoint_factor` parameter controls the position of the column at which
+ore eminates from. If 1, columns grow upward. If 0, columns grow downward. If 0.5,
+columns grow equally starting from each direction. `column_midpoint_factor` is a
+decimal number ranging in value from 0 to 1. If this parameter is not specified,
+the default is 0.5.
+
+The ore parameters `clust_scarcity` and `clust_num_ores` are ignored for this ore type.
+
+### `puff`
+Creates a sheet of ore in a cloud-like puff shape.
+
+As with the `sheet` ore type, the size and shape of puffs are described by
+`noise_params` and `noise_threshold` and are placed at random vertical positions
+within the currently generated chunk.
+
+The vertical top and bottom displacement of each puff are determined by the noise
+parameters `np_puff_top` and `np_puff_bottom`, respectively.
-This is essentially an improved version of the so-called "stratus" ore seen in
-some unofficial mods.
### `blob`
Creates a deformed sphere of ore according to 3d perlin noise described by
`noise_params`. The maximum size of the blob is `clust_size`, and
`clust_scarcity` has the same meaning as with the `scatter` type.
-### `vein
+
+### `vein`
Creates veins of ore varying in density by according to the intersection of two
instances of 3d perlin noise with diffferent seeds, both described by
`noise_params`. `random_factor` varies the influence random chance has on
Useful for having ore in sky realms without having to duplicate ore entries.
+### `puff_cliffs`
+If set, puff ore generation will not taper down large differences in displacement
+when approaching the edge of a puff. This flag has no effect for ore types other
+than `puff`.
+
+### `puff_additive_composition`
+By default, when noise described by `np_puff_top` or `np_puff_bottom` results in a
+negative displacement, the sub-column at that point is not generated. With this
+attribute set, puff ore generation will instead generate the absolute difference in
+noise displacement values. This flag has no effect for ore types other than `puff`.
