Terrain Editor

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 Import, Generate, and Clear tools.

Import

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

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.

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.

Select

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.

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

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.

Fill

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

Sea Level

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

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.
Source 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.

Option	Description
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.
Strength	Sets the brush strength from 0.1 to 1.
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.
Auto Material	Uses the same terrain material in the brush's vicinity when adding new terrain.
Source Material	Sets the material for Add mode.

Smooth

The Smooth tool smoothes out abrupt edges in terrain using the brush. This tool can be used in standalone mode, or you can toggle it on by holding Shift while using the Draw or Sculpt tools.

Option	Description
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.
Strength	Sets the brush strength from 0.1 to 1.
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 smoothing terrain.
Ignore Parts	Ignores parts in regards to brush placement while moving the mouse pointer across part surfaces.

Paint

The Paint tool, using the brush, paints a terrain material over an existing material or replaces one material with another material.

Option	Description
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 flattening terrain.
Ignore Parts	Ignores parts in regards to brush placement while moving the mouse pointer across part surfaces.
Material Mode	Toggles the tool between Paint and Replace mode. In Paint mode, choose the desired painting 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.

Flatten

The Flatten tool flattens terrain to a consistent level across a visualized plane. By default, the tool lowers terrain above the plane and raises terrain below to the plane, but you can opt to selectively lower or raise through the tool's Flatten Mode option.

Option	Description
Brush Shape	Sets the brush shape to either a sphere, box, or cylinder.
Flatten Mode	Erode to Flat¹ flattens terrain above the plane. Grow to Flat² fills in terrain below the plane. Flatten All³ removes terrain above the plane and fills in terrain below the plane.

Strength	Sets the brush strength from 0.1 to 1.
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.
Flatten Plane	If set to Fixed, flattens terrain to a fixed visual plane in Y world space.
Ignore Water	Ignores water when flattening terrain.
Ignore Parts	Ignores parts in regards to brush placement while moving the mouse pointer across part surfaces.
