Hi AlejFis. Thanks for posting the Aircreation pic. Just FYI, I do not have internet access at home (I access the internet using a public access point in town), so cannot test any of my aircraft in multiplayer scenarios.
This is most odd. My Aircreation model does not include code for displaying a default Flight pilot, so I'm surprised to see one. The fact that the pilot only appears in multiplayer, and only for other players (i.e. not one's own aircraft) is interesting. Flight may "assume" that, in multiplayer mode, there will always be a Flight pilot as part of the model. The fact that the pilot is shown in the position of the default "standing" mesh (i.e., it is not using a granny transform to make the pilot "sit") suggests that the multiplayer code might be written to always display a multiplayer user's avatar as the pilot, and not finding any pilot code, reverts to the default mesh for that users avatar.
Does anyone see a similar problem with my Beech Baron or Extra when flying with others in multiplayer? Both have Flight pilots included in the simdata code for the model.
w.r.t. comment by BergSpreu69 of his Sus Scrofa SS-4P having a similar problem: Now that I've seen the picture of the Aircreation, This would back up my hypothesis above, if he had not included the two CrewStations .simdata files in his model. In that case, if I'm right, he would not see any Flight pilot in his aircraft, but would see a "standing" Flight pilot in other multiplayer aircraft.
If I'm right, since we cannot change the multiplayer code for Flight, one solution would be to always include a Flight pilot in a converted FSX model. This itself is a problem if one cannot remove the FSX pilot (if it exists) prior to conversion. In this case an option might be to position the Flight pilot in the co-pilot seat of the aircraft (or, in the case of the Aircreation, in the rear seat). I have not tested this, though.
regards,
FS Tester.
