The original coords are not lost at the moment. They are retained in non-BP exposed way, as we are using double precision.
You can shift the asset to its original location by:
- calling RestoreOriginalCoordinates on the asset (available in BP)
- opening the asset editor (double-click the asset), then toggling the Center option from the toolbar twice (the first will center the pivot, the second will reset the pivot to its original coordinate)
If you reset multiple assets like this, they should still align well in UE just that it won’t be around the 0,0,0 location, but rather at the location at which they were exported.
