Terrain Editor

The Terrain Editor lets you easily generate and alter terrain through its Create, Region, and Edit tools.

Create Tab

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

Tool Description
Generate

Allows you to set a map position and size, choose biomes, then generate a randomized terrain with a unique seed (ID) through the following settings:

  • Position – Sets the position of the terrain within the experience.
  • Size – Sets the size of the terrain in studs.
  • 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

Allows you to import heightmaps and colormaps through the following settings:

  • Heightmap – Imports a heightmap.
  • Position – Sets the position of the terrain within the experience.
  • Size – Sets the size of the terrain in studs.
  • Material – Sets the material of the imported terrain.
  • Colormap – Imports a colormap to use alongside a heightmap.
Clear Lets you clear all terrain within the experience.

Region Tab

The Region tab is made up of the following tools and settings:

Tool Description
Select Lets you select an area of terrain so you can move, resize, rotate, copy, delete, or fill it with a specified material.
Move Lets you move the selected area to a new position. When the Merge Empty setting is enabled, the moved region is merged with surrounding terrain.
Resize Lets you scale the selected area to a new size. When the Merge Empty setting is enabled, the scaled region is merged with surrounding terrain.
Rotate Lets you rotate the selected area to a new orientation in 90° increments. When the Merge Empty setting is enabled, the rotated region is merged with surrounding terrain.
Copy Copies the selected area so that it can be duplicated (pasted).
Paste Pastes a copied area to a new selected location.
Delete Deletes the selected area.
Fill Lets you fill all voxels in the selected area with a chosen material.

Edit Tab

The Edit tab is made up of the following tools:

Tool Description
Add Quickly adds terrain based on the brush settings.
Subtract Quickly subtracts terrain based on the brush settings.
Grow Gradually adds terrain on top of other terrain.
Erode Gradually carves away terrain from other terrain.
Smooth Smooths terrain to get rid of sharp corners.
Flatten Flattens terrain using the special Flatten Mode brush setting.
Paint Paints a new material on top of any previously set material.
Sea Level Lets you create a consistent water level or remove (evaporate) all water within a region.
Replace Lets you replace a source material with a target terrain material, either within a box area or using a brush.

All of the above tools, with the exception of Sea Level, share the following brush and material settings:

Setting Description
Shape Sets the brush shape to either a sphere, cube, or cylinder.
Base Size Sets the brush size from 1 to 64.
Height Sets the brush height from 1 to 64. This setting is only available for the cube or cylinder brush shape.
Strength Sets the brush strength from 0.1 to 1. This setting is only available when using Grow, Erode, Smooth, or Flatten.
Flatten Mode

Only available when using the Flatten tool.

  • Erode to Flat – Flattens terrain above the plane.
  • Grow to Flat – Fills in terrain below the plane.
  • Flatten All – Removes terrain above the plane and fills in terrain below the plane.
Pivot Position Sets the vertical anchor point of the brush to either the bottom, center, or top of where the brush connects with the existing terrain.
Plane Lock

When editing terrain with the visual plane enabled, the brush stays locked to the plane. The following options control how plane editing behaves:

  • Off – Disables the plane entirely.
  • Auto – The plane tilts and rotates with the camera.
  • Manual – Lets you set a specific position and orientation for the plane.
Snap to Voxels Snaps the brush to the nearest voxel.
Ignore Water Ignores water when adding or subtracting terrain.
Ignore Parts Ignores parts when subtracting terrain.
Auto Material Blends new terrain with surrounding terrain. This setting is only available when using the Add or Grow tools.
Material Sets the material for the edit tool.
