The camera is locked in relation to the reported lon/lat/alt. So it is actually in the same position inside the model all the time (the camera of course can be moved but it is always in reference to the reported lon/lat/alt position). Well yes the problem really is that the FDMs are reporting the position data differently. The origins are different and it makes it impossible to share 3D Model configurations between different FDMs. The other problem that David brought up which I didn't understand at first is the CG is variable and therefore the FDM origin is variable, and we aren't taking that into account in the modeling. My opinion is that problem would be sufficiently resolved if the lon/lat/alt was reported from a fixed point on the aircraft.
