Hello, I have a number of aircraft that do not become visible when created as AI aircraft by certain tools like Traffic explorer, FSHOST, FS Recorder. The aircraft entry exist in the AI list, yet the visual model does not become visible. Otherwise, selected as user aircraft, they work perfectly. Does anybody have a clue on this? PS: Sorry, should have provided all available information. This happens in FSX/SP2 and is apparently related to the .MDL and/or textures of the aircraft, which are all either 3rd party or migrated FS9 aircraft.
