Applies a specified brush to the terrain at position 1 with a given height and a given size. Multiple brushes exist (see [`//sculptlist`](#sculptlist)) - and are represented as a 2D grid of values between 0 and 1, which are then scaled to the specified height. The terrain around position 1 is first converted to a 2D heightmap (as in [`//convolve`](#convolve) before the brush "heightmap" is applied to it.

If you've created a cool new brush (be it static or dynamic), **please contribute it to WorldEditAdditions**! That way, everyone can enjoy using your awesome brush. [WorldPainter](https://www.worldpainter.net/) has many brushes available in the community, but `//sculpt` for WorldEditAdditions is new so don't have the same sized collection yet :-)
To contribute your new brush back, you can either [open a pull request](https://github.com/sbrl/Minetest-WorldEditAdditions/pulls) if you're confident using GitHub, or [open an issue](https://github.com/sbrl/Minetest-WorldEditAdditions/issues) with your brush attached if not.
