Places `<node_name_a>` in the last contiguous air space encountered above the first non-air node. In other words, overlays all top-most nodes in the specified area with `<node_name_a>`.

|

Finds the first non-air node in each column and works downwards, replacing non-air nodes with a defined list of nodes in sequence. Like WorldEdit for Minecraft's `//naturalize` command, and also similar to [`we_env`'s `//populate`](https://github.com/sfan5/we_env). Speaking of, this command has `//naturalise` and `//naturalize` as aliases. Defaults to 1 layer of grass followed by 3 layers of dirt.

The list of nodes has a form similar to that of a chance list you might find in `//replacemix`, `//overlay`, or `//mix` - see the examples below. If the numberr of layers isn't specified, `1` is assumed (i.e. a single layer).

## `//forest [<density>] <sapling_a> [<chance_a>] <sapling_b> [<chance_b>] [<sapling_N> [<chance_N>]] ...`
|
||||
Plants and grows saplings to generate a forest. A density value is optionally taken, which controls the overall density of the forest that is generated. The `bonemeal` mod is required - just like for the [`//bonemeal`](#bonemeal-strength-chance) command.
|
||||
|
||||
The density defaults to 1, acts like a multiplier, and is not affected by the chances of all saplings listed (e.g. you can have a sapling with a chance of 1-in-50, and the overall density of the forest will be unaffected). For example, 2 results in a forest twice as dense as the default, and 0.5 a forest half as dense as the default density.
