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

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

Option | Description |
---|---|
Biomes | Includes the selected biomes in the generated terrain. |
Biome Size | Sets the size of the biomes within the overall terrain size. |
Caves | Includes caves in the generated terrain. |
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. |
Import
The Import tool imports a heightmap and optional colormap and applies them to a region selected by the Select tool.




Option | Description |
---|---|
Heightmap | Imports a heightmap from a local image file. |
Material | Specifies one consistent material to apply across all of the generated terrain. This is overridden by materials based on the colormap, if imported. |
Colormap | Imports a colormap from a local image file to use alongside a heightmap. |
Clear
The Clear tool opens a confirmation prompt to clear all terrain within the entire place.

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

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

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.

Option | Description |
---|---|
Position | Sets specific X/Y/Z values for the selection's position. |
Size | Sets specific X/Y/Z values for the selection's size in studs. |
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. |

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

Option | Description |
---|---|
Material Mode | Toggles the tool between Fill and Replace mode. In Fill mode, choose the desired fill material from the tool's picker tiles. In Replace mode, choose both the source material to replace and the target material to replace it with. |

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.

Option | Description |
---|---|
Brush Mode | Toggles the tool between Add and Subtract mode. Also toggled by holding down Ctrl or ⌘. |
Shape | Sets the brush shape to either a sphere, box, or cylinder.![]() |
Base 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. |
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. |
Snap to Voxels | Snaps the brush to the nearest voxel. |
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 | Sets the material for Add mode. |
Sculpt
The Sculpt tool adds or subtracts terrain using the brush. Unlike the Draw tool, this tool includes a strength slider/input to allow for more gentle manipulation of terrain. This tool functions in a dual mode where holding down Ctrl or ⌘ toggles on "subtract" mode instead of the default "add" mode, and holding down Shift temporarily activates the Smooth tool.
