I have a model of a mosque in Tanzania that is a combination of aerial photos captured by a drone (with GPS EXIF data) plus spherical photos captured inside by a 360 camera. The results look great in Agisoft, however when I export it the model is comprised of very coarse bands. This happens regardless of format (OBJ, STL, etc.), regardless of what program I use to view the file (Meshmixer, Slic3r, etc.) & regardless of the quality setting of the export (at default 'binary encoded' the file is just over 100MB, if I uncheck that box & enter '10' for quality the file is around 1GB but looks exactly the same).
I have successfully exported a model of a different building from this same trip, using the same settings, but which was just aerial photos, so I assume the problem has something to do with the fact that this time around I have two merged chunks from different cameras, one with location EXIF & one without, one a frame camera & the other equirectangular, etc.?
