Terrain Editor

The Terrain Editor, accessible from the toolbar's Home tab, lets you generate and manipulate environmental terrain through its Create and Edit toolsets.

For detailed instructions on working with terrain, see the Terrain guide.

Create tab

The Create tab includes the Import, Generate, and Clear tools.

Import

The Import tool imports a heightmap and optional colormap and applies them to a selected region.

Selection settings
Size, position, and snapping options as outlined for the Select tool.
Heightmap settings
Heightmap	Imports a heightmap from a local image file.
Colormap	Imports a colormap from a local image file to use alongside a heightmap.
Default Material	Specifies one consistent material to apply across all of the generated terrain. This is overridden by materials based on the colormap, if imported.

Generate

The Generate tool procedurally generates terrain within a selected region. This is useful if you want to create a large map and then fine-tune terrain details using the Edit tab tools.

Selection settings
Size, position, and snapping options as outlined for the Select tool.
Biome settings
Biomes	Includes the selected biomes in the generated terrain.
Blending	Adjusts how the biomes blend into one another, with higher values a bit smoother.
Caves	Includes caves in the generated terrain.
Biome Size	Sets the size of the biomes within the overall terrain size.
Seed	A number that Studio generates to determine the shape of the terrain. When you change this number, Studio generates a new terrain with the same settings.

Clear

The Clear tool reveals a button that clears all terrain within the entire place.

Edit tab

The Edit tab includes the Select, Transform, Fill, Sea Level, Draw, Sculpt, Smooth, Paint, and Flatten tools.

The Select tool is a universal tool for selecting rectangular regions of terrain. With the tool enabled, select a region by clicking and dragging in the 3D viewport, reposition it with the move draggers, and edit its size with the scale handles. Alternatively, enter values into the tool's X/Y/Z inputs to set a specific position and size.

Select tool indicated in Edit tab of Terrain Editor

Selection settings
Size	Sets specific X/Y/Z values for the selection's size, in studs.
Position	Sets specific X/Y/Z values for the selection's position.
Snap to Voxels	Snaps the selection bounds to the nearest voxel.

Move draggers and scale handles on a selected region

Studio also supports the following keyboard and mouse shortcuts, assuming the Select tool is active and nothing is selected in the Explorer hierarchy.

Windows	Mac	Action
CtrlC	⌘C	Copy terrain within the selected region to the clipboard.
CtrlV	⌘V	Paste terrain that has been copied to the clipboard and swap to the Transform tool so that the new terrain can be transformed.
CtrlX	⌘X	Cut terrain within the selected region to the clipboard.
CtrlD	⌘D	Duplicate terrain within the selected region and swap to the Transform tool so that the new terrain can be transformed.
Delete	Delete	Delete terrain within the selected region.
Shift	Shift	When held down while dragging any scale handle, scales the region proportionally across all other axes.
Ctrl	⌘	When held down while dragging any scale handle, scales the region equally in both the positive and negative direction along that axis.

Transform

The Transform tool manipulates entire selected regions to a new position, size, or orientation. With the tool enabled, transform a selected region with the move draggers, rotate rings, and scale handles. Alternatively, enter values into the tool's X/Y/Z inputs to set a specific position, size, and rotation.

Transform settings
Size	Sets specific X/Y/Z values for the selection's size in studs.
Position	Sets specific X/Y/Z values for the selection's position.
Rotation	Sets specific X/Y/Z values for the selection's rotation in degrees.
Merge Empty	When enabled, air voxels in the selection will overwrite existing voxels at the destination.
Live Edit	When enabled, terrain is constantly updated while being transformed. To view only a wireframe preview of the transformation, disable live edit mode and then, while transforming, press Enter/Return or click the Apply button to apply the changes.
Snap to Voxels	Snaps the selection bounds to the nearest voxel.

Move draggers, rotate rings, and scale handles on a selected region

Before rotating a region with the visual rotate rings, check the rotation snapping setting in Studio's toolbar. Disable rotation snapping entirely for free-form rotation.

Similar to selecting a region, holding Shift while dragging any scale handle scales the region proportionally across all other axes, and holding Ctrl or ⌘ while dragging scales the region equally in both the positive and negative direction along that axis.

Fill

The Fill tool fills an entire selected region with a specific material, or replaces all material within the region with another material.

Selection settings
Size, position, and snapping options as outlined for the Select tool.
Material settings
Fill Mode	Toggles the tool between Fill and Replace mode.
Source Material	In Fill mode, the desired fill material. In Replace mode, the material to replace.
Target Material	In Replace mode, the material to replace the source material with.

Region filled with Salt material — Selected region filled with Salt material

Sea level

The Sea Level tool lets you create a consistent water level or remove all water within a region.

Sea level settings
Size	Sets specific X/Y/Z values for the selection's size in studs.
Position	Sets specific X/Y/Z values for the selection's position.
Snap to Voxels	Snaps the selection bounds to the nearest voxel.

Draw

The Draw tool adds or subtracts terrain using the brush. This tool functions in a dual mode where holding down Ctrl or ⌘ toggles on "subtract" mode instead of the default "add" mode. Additionally, holding down Shift temporarily activates the Smooth tool.

Brush settings
Brush Mode	Toggles the tool between Add and Subtract mode. Also toggled by holding down Ctrl or ⌘.
Brush Shape	Sets the brush shape to either a sphere, box, or cylinder.
Brush Size	Sets the brush size from 1 to 64. If you choose a brush shape of box or cylinder, a Height slider/input also appears to adjust the brush height proportionally or independently of the base size.
Pivot Position	Sets the vertical pivot point of the brush to either the bottom, center, or top of where the brush connects with existing terrain.
Snapping	Whether snapping is off or to the nearest voxel.
Plane Lock	Toggles whether to enable a visual plane which the brush locks to. In Auto mode, the plane tilts and rotates with the camera. In Manual mode, the Edit Plane option appears, letting you set a specific position/orientation through the visual draggers or X/Y/Z inputs.
Ignore Water	Ignores water when adding or subtracting terrain.
Ignore Parts	Ignores parts in regards to brush placement while moving the mouse pointer across part surfaces.
Material settings
Auto Material	Uses the same terrain material in the brush's vicinity when adding new terrain.
