Hi @Jignaciobg
This should be possible if you know where the north is.
RealityCapture uses the axes as X is pointing to the east and Y to the north. So using some coordinates around your model (as [1,0] for the point on the east side of your model, [0,1] for the point on the north side of your model and [-1,0] for the point on the west side of your model) should orient your model properly to the north. You can also use the proper values to get your model scaled.
