Declaration

UCLASS()
class UOrreryTerrainHeightmapImport : public UBlueprintFunctionLibrary

Header: #include "OrreryTerrainHeightmapImport.h"
Module: PublicDependencyModuleNames.Add("OrreryTerrainEditor"); in an editor module’s Build.cs: an editor module, not in packaged games.
Stability: Stable: changes within a major version only add.
Derives from: UBlueprintFunctionLibrary
Blueprint: “Orrery Terrain Heightmap Import”, a Blueprint type

Description

Heights become whole centimetres (llround of z_offset_m + sample * metres_per_unit, in centimetres), exactly as UOrreryTerrainHeightmapSourceAsset does, so the store equals that asset's tiles for the same samples. Nodata samples take the nearest valid sample of their row (FRasterTiler). The store is built by FOrreryTerrainTileStoreBuilder::BuildFromRaster.

Integer decode and a fixed order throughout: the same input and options give the same store hash.

Functions
