Variables

	Name	Description
bool	bOriginAtPlanetCenter	If true, the UE origin is located at the Planet Center, otherwise, the UE origin is assuming to be defined at one specific point of the planet surface, defined by the properties below.
bool	bOriginLocationInProjectedCRS	If true, the UE origin georeference is expressed in the PROJECTED CRS.
FString	GeographicCRS	String that describes the GEOGRAPHIC CRS of choice.
int32	OriginAltitude	Altitude of UE Origin on planet
int32	OriginLatitude	Latitude of UE Origin on planet
int32	OriginLongitude	Longitude of UE Origin on planet
int32	OriginProjectedCoordinatesEasting	Easting position of UE Origin on planet, express in the Projected CRS Frame
int32	OriginProjectedCoordinatesNorthing	Northing position of UE Origin on planet, express in the Projected CRS Frame
int32	OriginProjectedCoordinatesUp	Up position of UE Origin on planet, express in the Projected CRS Frame
EPlanetShape	PlanetShape	This mode has to be set consistently with the way you authored your ground geometry.
FString	ProjectedCRS	String that describes the PROJECTED CRS of choice.
