It would be cool if MS could handle ntv2 planimetric coordinate conversion (Eg. like proj and epsg:4326 <-> epsg:31468 with BeTA2007 grid).
In fact for the moment i can transform cameras from dji p4rtk 4326 in 31468 With beta2007 with proj lib, and make the photogrametric processing in 31468. But when i want to export cloud or mesh to cesium (only wgs) MS make helmert (ToWGS) and WE loose précision.
Thanks Agisoft team if you could integrate proj lib or pyproj in metashape
