bool bOriginLocationInProjectedCRS
If true, the UE origin georeference is expressed in the PROJECTED CRS. (NOT in ECEF ! - Projected worlds are the most frequent use case...) if false, the origin is located using geographic coordinates.
WARNING : the location has to be expressed as Integer values because of accuracy. Be very careful about that when authoring your data in external tools !
