Not sure why you need to include the whole model file? Just alias it. Distributing a modified model file does not sound like a particularly good idea especially without permission of the original devleoper.
Adding via the FSX way is hacky and requires the user to do more. We should be looking at this new way as the future (and it is). Why are you trying to go backwards?
And your point? I use the registration NOVA24. Its there as a placeholder for users to set what they want. Are you going to police every user of your livery to make sure they ONLY use a VALID registration number? Let ASobo have their marketing.
The whole model file - because it works for me atm. I have no plans on sharing my work until I can figure out what I am doing wrong. Why do some megapack liveries seem to work, when mine don't despite having an identical layout as far as I can see - and I have been checking since day one. I found one fault once where I had a period instead ov a comma. The only thing I am left with now is having 4096 hi-res dds images that are larger than the Asobo standard. I might have to edit in the exact flle size into those ....DDS.json files and also find out how the creation date conventions work.
The FSX way was never hacky in FSX, and since the orbx marketed aircraft all live in the community folder, then the fallback coding really is straightforward. Like I say - I won't know till I try.
So you use a personal and fictional Identification. I have no problems with that. But it is not real-world authentic, and when I do paints of realworld aircraft, they are primarily with the owner's express permission so that the liveries reflect that aircraft as realisticall as possible (and save me from getting copyright lawsuits filed against me). And if my liveries are fictional, then so are my registrations - I do check international registries wherever I can. For me "Authentic" is the be all and end all. of a repainter's true worth. As for policing every user - Do be brief, man! If microsoft couldn't do it... but they never publishe a livery or model without clear reference to copyrights and granted permissions from the realworld counterparts. Airbus, Boeing, Kenmore seaplanes... and neither Fs 9 to FSX nor msfs have ever been different. They are spotless as far as possible, with what they sell.
Anyway, that is just my view on repainting. Will I be sharing mine? Possibly - if I live long enough. Just like I shared the hundreds I have already shared. And yes, some of mine did break the copyright rulings. And yes, I did have problems with one copyright holder threatening a "cease and desist". But since then, any of my liveries all had the owner's seal of approval. From Patty Wagstaff through many more. And I do warn the owners that I don't wish to be held accountable if my liveries are bu66ered around with.
Yeah - I am a nut job. I don't care what anyone else does...
Picture attached - fictional w-i-p The next time you see it, it will hopefully be in-sim (health willing)
