Unreal Engine 5 Documentation has been moved to the Epic Developer Community

In Manage Mode, you can create new Landscapes and use the component tools to modify an existing Landscape's components. You can also select components and modify their properties in the Details panel.

For information about creating Landscapes, see Creating Landscapes .

Landscape Selection

In the Landscape panel, select which Landscape to modify from a list of all the Landscapes currently in your level.

To select a Landscape:

• In the Landscape panel click the Landscape drop-down box in the Landscape Editor section to display a list of all Landscapes currently in the map.

• Choose the Landscape you want to edit.

Selecting a Landscape from the list makes that the active Landscape. All subsequent editing will then be applied to that Landscape.

Components

Components are the building blocks of any Landscape Actor. You can work with them using the Component tools and adjust their properties individually in the Details panel.

Component Tools

The tools described below act on the component level of the currently selected Landscape.

Selection

The Selection tool selects Landscape components for subsequent use with other tools, such as moving them to a streaming level or deleting components.

The selection cursor is always limited to one component:

When components have been selected, they become shaded red:

Add

The Add tool creates new components for the current Landscape, one at a time.

When the Add Landscape Component tool is active, the cursor shows a green wireframe where new components can be added:

Using the tool adds a new component where the cursor is located:

Delete

The Delete tool deletes any selected components.

Using the tool removes the selected components:

Move Level

This tool moves the selected components, via using the Selection tool, to the current streaming level. This makes it possible to move sections of a Landscape into a streaming level so that they will be streamed in and out with that level, optimizing the performance of the Landscape.

When the streaming level is visible, the Landscape renders all the components:

You can toggle the visibility of the level by clicking the eye icon ( ) for that level in the Levels panel (accessible on the Level Editor's Window menu). Doing so causes the components in that level to no longer be rendered:

Edit Splines

For information about how to create and modify spline curves, see Landscape Splines .

Component Properties

You can set the properties of individual components, including LODs and component-specific Materials, in the Details panel.

Component LODs

You can also set LODs for selected component, which means an individual component can have its own LOD settings.

To set LODs for selected component:

1. Select the components whose LODs you want to set. For information about selecting components, see Selection .

2. In the Details panel, under Landscape Component , adjust the Forced LOD and LODBias settings to obtain the desired result.

Component Material Overrides

You can set a Material Override for selected components, which means that an individual component can have a different Material assigned to it than its Landscape does.

To set a Material Override for selected components:

1. Select the components that you want to use a different Material for. For information about selecting components, see Selection .

2. In the Content Browser , find and select the Material you want to use.

3. In the Level Editor's Details panel, under Landscape Component , click the Assign arrow icon (

   
   ) to assign that Material to the selected components.
