Parameters

Name	Type	Default	Meaning
`WorldContextObject`	`const UObject*`	—	Any object in the world whose terrain is read; supplies the world.
`Locations`	`const TArray<FVector>&`	—	World cm. Up to 65,536 per call; the rest are answered NoData, with a warning in the log.
`Fields`	`int32`	—	A bit mask of `EOrreryTerrainSampleFields`; the height is always computed.
`Accuracy`	`EOrreryTerrainAccuracy`	`EOrreryTerrainAccuracy::Best`	Best, ExactOnly or Coarse (`EOrreryTerrainAccuracy`).
`Surface`	`EOrreryTerrainSurface`	`EOrreryTerrainSurface::Modified`	Which ground to read (`EOrreryTerrainSurface`); Modified is the current ground.

Note.

Use this over a loop of SampleGround: one snapshot, one pass.
