What it does

Alt inverts the stroke.

Averages within the brush kernel.

Ctrl and right click samples the target height.

Wears down exposed edges.

Levels toward the local gradient.

Cuts ridgelines rather than whole areas.

Increases local contrast in the height field.

Steps the terrain into bands.

Shift bulges instead of pinching.

Shift reverses the direction.

Follows the direction of the stroke.

Shift and click sets the sample area.

Places a heightfield; Alt inverts it.

Shift and click sets the start, then one shot.

Droplet simulation that also paints its sediment into the splat layer.

Writes an absolute elevation.

Any of the four paintable layers.

On topology and alpha.

Averages from a snapshot, so blended texels cannot feed back into their neighbours.

Moves weight between channels rather than copying it, so the texel total is preserved.

Reads the whole source first, so a clone overlapping its own source copies the original.

Height range, slope range and splat, biome and topology filters, all applied together.

Paint several topology bits in one stroke.

Save and reapply named bit masks.

Position, rotation and scale, with an undo stack.

Scatter from a palette with per-item scale and rotation.

Load and place saved prefab files.

Connections are stored by path and position, as the game reads them.

Profiles you can edit and assign to a selection.

Typed spawners the server extension honours.

Authored from the editor with full node handles.

Add, insert, delete, split and drag, with per-node bezier handles.

Shows the resampled nodes the game will actually use.

The water layer is rewritten on save from the river paths.

All seven layers, prefabs and paths.

Fully compatible, including encrypted blob names.

Rotate, resize and merge a region from another map.

Single layers as .redata, heightmaps as images.

Rendered overview with biomes, monuments and a grid.

On a clock, writing extension edits before the backup.
