Landscape Spawner

Landscape Spawner#

Landscape Spawner Overview#

  1. Search for LandscapeSpawner in the Content Browser, and drag one in your landscape. You can have several LandscapeSpawner’s in your level.

  2. Choose the heightmap source that you want in the Heightmap Downloader component (the LandscapeCombinatorMap in the Plugin’s Content contains several LandscapeSpawner examples).

  3. In the Details Panel of the LandscapeSpawner, you can check the “Create Mapbox Decals” or “Create Custom Decals” options if you also want to create decals. “Create Custom Decals” uses the Image Downloader settings from the Texture Downloader component.

  4. If you prefer to keep the creation of decals separated, you can use Landscape Texturer actors after (or before) your landscape has been created.

  5. In the Details Panel of the LandscapeSpawner, click on Spawn Landscape.

Landscape Spawner Settings#

General

  • Spawn Method (ESpawnMethod, default Create Fresh Landscape)

    • Create Fresh Landscape

    • Create Fresh Landscape Incrementally

    • Extend Existing Landscape: This option lets you extend an existing landscape. It will apply the heightmaps to the landscape. It will add components as necessary to extend the landscape if the downloaded heightmaps extend beyond the current landscape size. The landscape needs to be already placed in the rough correct location for the downloaded heightmaps.

  • Landscape To Extend Selection (FActorSelection)

  • Landscape Label (FString, default "SpawnedLandscape"): Label of the landscape to create.

  • Landscape Tag (FName, default "lc"): Tag to add on the spawned landscape.

  • Landscape Material (UMaterialInterface): Material to apply to the landscape

  • Create Landscape Streaming Proxies (bool, default false): If you are using World Partition, check this option if you want to create landscape streaming proxies. This is useful if you have a large landscape, but it might slow things down for small landscapes. When using this option, it’s important to use a preset for the component counts, or the generation will freeze or be very slow.

  • Spawned Actors Path (FName): Folder used to spawn the actors. This setting is unused when generating from a combination or from blueprints.

  • Z Scale (double, default 1): The scale in the Z-axis of your heightmap, ZScale = 1 corresponds to real-world size.

Blending

  • Blend Landscape With Another Landscape (bool, default false): This is used if you want to create a “hole” in another, larger background landscape, so that the newly spawned landscape doesn’t get hidden by the background landscape.

  • Blend Landscape (UBlendLandscape)

Decals

  • Decal Creation (EDecalCreation, default None)

    • None

    • Mapbox

    • MapTiler

  • Decal Material (UMaterial)

  • Decals Mapbox Zoom (int, default 9)

  • Decals Map Tiler Zoom (int, default 9)

Component Count

  • Components Method (EComponentsMethod, default Auto Without Border)

    • Manual: Enter the Quads Per Section, Section per Components, and Components Counts manually

    • Auto Without Border: When the landscape components do not exactly match with the total size of the heightmaps, Unreal Engine adds some padding at the border. Check this option if you are willing to drop some data at the border in order to make your heightmaps match the landscape components.

    • Auto: Let Unreal Engine decide the component count based on the heightmap resolution.

    • Preset 8129 8129

    • Preset 4033 4033
