I wish you would of referred me to this link in the first place (would of saved a LOT of back and forth):
There wasn't any need for it, since the correct answer was already in my initial reply. I repeat it again: if the plane is configured as Cargo, you wouldn't see any passengers, and you'll see the Loadmaster guy in addition to the two pilots.
An no this C-47 is not configured as cargo? The dude on the link I provided said same thing....
yes, it IS configured as Cargo, otherwise you wouldn't see the Loadmaster!
Maybe this wasn't entirely clear to you but, when I said "Configured as Cargo", I mean
IN GSX in the Airplane configuration page. That's the only place were you can tell to GSX is an airplane is Cargo.
NOTHING in the aircraft.cfg file is used by GSX to decide if an airplane is Cargo or not. The one and only place were GSX is told if an airplane is Cargo, is the GSX Airplane customization page. By default, all airplanes are configured as passengers so, unless that airplane is already internally supported by GSX (and I'm sure it's not), the only possible reason why GSX thinks this is a Cargo airplane, it's because you said so. Or, possibly, it already came with a GSX.CFG file in its folder that set it as Cargo.
And no, the link you found, is not relevant at all to your case, first because it was from 2016, when passengers didn't exist but, also because you displayed a screenshot showing the Loadmaster, and that's a tell-tell the airplane IS flagged as Cargo. We didn't had the Loadmaster either in 2016 so, my reply is correct to the current situation.
When the airplane is flagged as Cargo, you can do *anything* to the payload, but you will still NOT see any passengers! Just the two pilots AND the Loadmaster guy.
If the airplane is NOT flagged as Cargo, you might still not see passengers, usually because the doors are not configured correctly, so no stairs will appear (no stairs = no passengers ), but you will NOT see the Loadmaster.
That's why, based on your report, I said you must have the airplane configured as Cargo, because you have the Loadmaster, and that one only comes when the airplane is configured as Cargo.
