UOrreryTerrainHeightmapImportSettings

What the heightmap import asks when the heightmap has no sidecar to say it: the scale and the extent (Tier 3, editor only).

Declaration

UCLASS(Transient)
class UOrreryTerrainHeightmapImportSettings : public UObject

Header: #include "Factories/OrreryTerrainFactories.h"
Module: PublicDependencyModuleNames.Add("OrreryTerrainEditor"); in an editor module’s Build.cs: an editor module, not in packaged games.
Stability: Experimental: supported, may change in a minor version, with a changelog line.
Derives from: UObject

Description

Shown in the import dialog. With a sidecar beside the file (<file>.json or <name>.json) nothing is asked and the sidecar rules; without one the values here become a sidecar the importer reads.

Functions

UpdateExtent
Recompute Extent_m from the size and the spacing.
MakeSidecarJson
The JSON sidecar these values make (size only for RAW).
Inspect
Read File and the sidecar beside it: sets Info, bHasSidecar, bIsRaw and FileSize.

`File`	`FString`	—	The file being imported.
`Info`	`FString`	—	What the file is: its size, or why it cannot be read.
