Tools

Every tool works in both the 2D and 3D views. Radius, strength, brush shape and rotation are adjustable, with optional altitude, slope and material constraints.

Press Escape to go back to the Hand tool at any time.

Navigation

Hand

Moves the view (pan) in 2D and 3D.

Control	Action
Left click + drag	Pan the view
Hold Space	Pan temporarily from any tool

Terrain sculpting

Raise / Lower

Raises or lowers the heightmap under the brush.

Control	Action
Left click	Raise the terrain
Right click	Lower the terrain

Smooth

Smooths heights locally.

Control	Action
Left click	Smooth the terrain
Right click	Roughen the terrain

Flatten

Levels the terrain toward the height where the stroke started.

Control	Action
Left click	Flatten toward the starting height

Painting

Paint

Paints the active layer (material, cover, object, resource or biome).

Control	Action
Left click	Paint the active layer
Right click	Erase the active layer only

Spray can

Paints with a probabilistic spray. The draw is deterministic, so passing again over the same cells gives the same result.

Control	Action
Left click	Spray the active layer
Right click	Erase the active layer only

Eraser

Erases the active layer under the brush. With no active layer selected, it becomes a master eraser and clears every layer.

Control	Action
Left click	Erase (scope = active layer, or everything if none)

Eyedropper

Reads what sits under the cursor and sets it as the active layer.

Control	Action
Left click	Open a popup listing the material / cover under the cursor

Global painter

Applies the active layer to the entire map, after a confirmation dialog.

Control	Action
Left click	Apply the active layer to the whole map

Fluids

Flood fill

Fills a connected basin with water or lava (fluid selectable in the tool options) up to the clicked level.

Control	Action
Left click	Fill the contiguous area at the clicked level
Right click	Lower the water level of the clicked area

Water has a global level and an optional per-cell override; a cell's effective level is the higher of the two.

Sponge

Removes the local fluid from a contiguous area.

Control	Action
Left click	Drain the contiguous fluid area

River

Draws a river as a curve with free control points, then carves the bed and lays the water in one go. Each point has width and depth handles.

Control	Action
Left click	Place a control point / drag a point or its handles
Right click	Delete the point under the cursor (and its branches)
Enter	Carve the bed and fill with water
Delete	Remove the selected point

Selection & clipboard

Select

Builds a cell selection with three shapes: rectangle, circle or lasso. The selection also acts as an edit mask: while active, other tools only apply inside it.

Control	Action
Left click / drag	Add to the selection
Right click / drag	Remove from the selection
Delete	Clear the selection
Escape	Leave the tool

Copy

Copies the selected zone. A popup asks what to copy (heights, layers, water…), then the tool switches to paste mode.

Control	Action
Left click / Enter	Apply the paste at the cursor
Right click / Escape	Cancel the paste

Objects

Place object

Places schematics one by one from the active object layer, with a translation gizmo. The selected object renders as a voxel ghost until confirmed.

Control	Action
Left click / drag	Place the object / move it with the gizmo
Right click	Deselect the placed object
R	Rotate the selected object by 90°
Enter	Confirm the placement
Delete	Delete the selected object

Utilities

Spawn point

Sets the player spawn point of the exported world.

Control	Action
Left click	Place the spawn at the clicked cell
Right click	Reset the spawn to the map center

Ruler

Measures distances between two points. Several measurements can coexist.

Control	Action
Left click + drag	Place and stretch a measurement
Right click	Clear all measurements
Delete	Remove the selected point

Annotation

Paints colored working notes over the map (rectangle, circle, lasso or text). Annotations are never exported.

Control	Action
Left click	Draw with the active color
Right click	Erase annotations
