Guia

The landscape kit creates and edits ALandscape actors of the editor world without opening Landscape Mode: heights, paint layers and weights, holes, edit layers, splines and grass types. Everything goes through public engine APIs (ALandscapeProxy::Import, FLandscapeEditDataInterface, ULandscapeInfo, ALandscape edit-layer calls, ULandscapeSplinesComponent). Water bodies are in the separate water kit (Water plugin).

Conventions:

landscape is the actor label, object name or path; read-only calls may omit it when the level has exactly one landscape. Start with landscape.list / landscape.get.
Region and brush coordinates are landscape vertex coordinates (0..N, inclusive regions), not world centimetres. landscape.get returns the vertex bounds; regions outside them are rejected.
Heights are landscape uint16 values (32768 = zero); weights are 0..255.
On a landscape with edit layers, height and weight tools write the active edit layer (landscape.set_active_edit_layer), or the first edit layer when none is active — never the merged result, so edits survive the next layer merge.

1. Create, inspect and sculpt

Coordinates: sculpt tools use landscape vertex coordinates and uint16 heights (32768 = actor Z; one unit = scale.Z/128 cm). Convert with landscape.world_to_vertex / vertex_to_world, or query in world units with landscape.sample_world (up to 1024 XY points → surface Z, normal, slope) and landscape.line_trace (this landscape's collision only; call update_collision after edits).

Building terrain from data: landscape.create_from_height_array takes a row-major height array of exactly (componentsX·sectionsPerComponent·sectionSizeQuads+1)² values; pass replace to rebuild an existing landscape in place, keeping its label, transform, material and settings. landscape.resample changes resolution but keeps the footprint (heights and paint weights resampled, X/Y scale adjusted). landscape.resize changes the component count (anchor corner|center, fillHeight or edge extension). landscape.duplicate copies heights, weights, material and settings to a new actor at offset. All four refuse world-partition landscapes (see list_proxies) and read only the first edit layer.

Shaping: stamp_shape (hill/cone/plateau/crater), flatten_path (road bed along a polyline; point z = target height or -1 to follow the terrain), stamp_height_region (set/add/max/min a block), noise_region (Perlin noise with seed/octaves/frequency), erode_region (thermal), scale_region, clamp_region, copy_region (also between landscapes), mirror_region (symmetric maps). Finish with recalc_normals, update_collision, rebuild_bounds.

Analysis: slope_map (degrees grid plus steep fraction), height_histogram, find_flat_spots (flattest vertices within slope/height limits, with world positions), get_bounds.

Settings: typed setters for LOD, lighting, collision (profile/overlap), navigation, rendering, virtual textures, bounds extension, physical material and hole material. Negative numbers and empty strings leave a value unchanged. Per-component: get_component_settings and set_component_{lod,lighting,collision_mip,bounds_extension,material_override} with sectionBaseX/Y or allComponents.

2. Paint layers and layer infos

A paint layer is a name backed by a ULandscapeLayerInfoObject asset. The landscape material decides which layer names it blends (Landscape Layer Blend nodes); the layer infos store the weights.

landscape.create_layer_info {folder, name, weightBlended} creates the asset; its paint-layer name is the asset name. landscape.add_paint_layer {landscape, layerInfo} assigns it (target layer on 5.5+, editor layer settings before).
landscape.auto_create_layer_infos {landscape, folder, names} creates <Layer>_LayerInfo assets and assigns them — for the given names, or for every layer of the landscape material when names is empty. Layers that already have an info are listed in skipped.
landscape.list_layers lists names, assets and blend mode; landscape.validate_layers warns about layers without an info and material layers that are not assigned.
landscape.replace_layer_info {landscape, layer, layerInfo} swaps the asset behind a layer; the painted weights move to the new info (it must not already be assigned).
landscape.remove_layer_info {landscape, layer} deletes the layer's weights and unassigns it (the asset stays).

3. Weights and holes

Read: landscape.get_weight (min/max/average over a region), landscape.get_weight_grid (row-major 0..255 values, at most 65536 vertices per call).
Write: paint_layer_region (constant box), paint_layer_circle (disc with falloff 0..1 of the radius; vertices outside the disc keep their weight), paint_layer_gradient (axis x or y), set_weight_grid (row-major values, the inverse of get_weight_grid), fill_layer (whole landscape), clear_layer (deletes the layer's weights, keeps the layer).
Weight-blended layers renormalise the other weight-blended layers of the same vertices, exactly as in Landscape Mode.
Holes: landscape.set_visibility_layer {landscape, minX..maxY, hidden} writes the engine visibility layer (hidden:true cuts, false restores). Holes render only with a material that has a Landscape Visibility Mask.
Files: landscape.export_weightmap {landscape, layer, file} writes .png or .raw through the engine exporter; landscape.import_weightmap {landscape, layer, file, minX, minY, width} reads an 8-bit .raw (row-major; width defaults to the landscape width, height = size / width). PNG import is not offered (no public decoder in the kit's dependencies).

4. Edit layers

UE 5.7+ landscapes always have edit layers. On older engines a landscape created without them needs landscape.enable_edit_layers (UE 4.27–5.6; converts the existing data into a default layer).

landscape.list_edit_layers — bottom-to-top stack with visible, locked, heightmapAlpha, weightmapAlpha, active, type and blueprint brushes.
add_edit_layer {name} (the engine makes names unique; read editLayer.name), remove_edit_layer (not the last one; clears the active selection if it pointed there), rename_edit_layer, reorder_edit_layer {layer, newIndex}, set_active_edit_layer {layer} (empty clears), set_edit_layer_alpha {layer, alpha, target:'heightmap'|'weightmap'} (heightmap -1..1, weightmap 0..1), set_edit_layer_locked, set_edit_layer_visible (enabled), clear_edit_layer {heightmap, weightmap} (refused on a locked layer).
landscape.list_blueprint_brushes lists the ALandscapeBlueprintBrushBase actors per layer (Water bodies appear here when they carve the landscape).

5. Splines

Control points and segments live in the landscape's ULandscapeSplinesComponent (created on the first point). Locations are landscape-local centimetres; indices come from spline_list and spline_list_segments and shift down after removals.

Points: spline_add_point, spline_set_point_transform (move/rotate), spline_set_width, spline_set_side_falloff, spline_set_point_settings (paint layer, raise/lower terrain, end falloff, mesh offset, point mesh — all fields written), spline_get_point, spline_list, spline_remove_point (also removes its segments).
Segments: spline_connect {startIndex, endIndex, startTangent, endTangent, layerName} (0 tangents = half the point distance with automatic flipping), spline_list_segments, spline_get_segment, spline_set_segment_tangents, spline_set_segment (paint layer, raise/lower), spline_set_mesh_entries (complete list of {mesh, scale, scaleToWidth, centerH, forwardAxis, upAxis}; empty clears), spline_remove_segment.
Whole network: spline_import_points {points, connect, closedLoop, layerName} appends a chain, spline_export_points returns points + segments (feed points back to import), spline_rebuild (meshes and collision), spline_apply (rasterises raise/lower and layer painting into the landscape — the splines edit layer when present; applied:false means nothing changed), spline_clear.

6. Grass

Types: grass_create_type {folder, name}, grass_list_types {folder}, grass_get_type (every variety, typed), grass_audit_type, grass_set_density_scaling.
Varieties (by index): grass_add_variety {mesh, density}, grass_remove_variety, grass_get_variety (every reflected property as text), grass_set_variety {settings:[{key,value}]} (FGrassVariety names, dotted paths such as GrassDensity.Default, ScaleX.Min; all keys are validated first and a parse error restores the variety), grass_set_scale (Uniform/Free/LockXY + ranges), and typed setters grass_set_density, set_start_cull, set_end_cull, set_min_lod, set_jitter, set_random_rotation, set_align_to_surface, set_grid, set_receive_decals, set_dynamic_shadow, set_contact_shadow (5.0+), set_landscape_lightmap, set_cpu_copy.
Materials: grass is spawned from a Landscape Grass Output node in the landscape material. landscape.list_grass_outputs {material | landscape} lists its pins and assigned grass types (edit the node with the material kit). landscape.grass_flush drops cached grass so it regenerates.

Recipes

Layered terrain in eight calls.

landscape.create {name:'Terrain', componentsX:4, componentsY:4, sectionSizeQuads:63}.
Sculpt with the region tools of section 1 (noise, terrace, smooth).
landscape.set_material {landscape:'Terrain', material:'/Game/M_Landscape'} (a layered material).
landscape.auto_create_layer_infos {landscape:'Terrain', folder:'/Game/Landscape/Layers'}.
landscape.fill_layer {landscape:'Terrain', layer:'Grass'}.
landscape.paint_layer_circle {landscape:'Terrain', layer:'Rock', centerX:100, centerY:100, radius:30, weight:255, falloff:0.5}.
landscape.spline_import_points {landscape:'Terrain', points:[...], connect:true, layerName:'Dirt'}.
landscape.spline_apply {landscape:'Terrain'}, then landscape.validate_layers.

Weight round trip. get_weight_grid a tile, change values, set_weight_grid with the same origin and width. For whole-landscape transfers use export_weightmap (.raw) and import_weightmap.

Non-destructive edits. add_edit_layer {name:'Roads'} → set_active_edit_layer {layer:'Roads'} → sculpt/paint → set_edit_layer_alpha to blend it, set_edit_layer_visible {enabled:false} to compare, clear_edit_layer to start over.

Gotchas

Layer names are case-sensitive FNames taken from the layer-info asset; create_layer_info names the layer after the asset, auto_create_layer_infos after the requested name.
Painting is visible only when the landscape material has a matching layer; weights are stored regardless.
remove_layer_info, replace_layer_info and enable_edit_layers run engine operations that may show a short progress bar; they do not open dialogs.
Spline indices are positions in the component arrays: re-read spline_list / spline_list_segments after removing points or segments.
enable_edit_layers is hidden on UE 5.7+, where every landscape already has edit layers.
