Bug Description
When setting the projection to equirectangular, the resulting panorama will get further exif (or xmp) tags giving more information of the projection, that apparently some image hosting websites use to show these in a 3d view. However, this feature is completely missing when the projection is something other than equirectangular.
Screenshot shows the ends of the output from exiftool of two panoramas of similar size but different projections.

According to the spec of GPano https:/ /developers. google. com/streetview/ spherical- metadata currently only equirectangular is supported for ProjectionType.
Also the values for FullPano*Pixels and CroppedArea*Pixels are only defined for a equirectangular projection. There are no conventions for these tags when using another projection and especially for partially panos in these projection.
So Hugin write the GPano tags only for equirectangular panos.
