There’s a reason you aren’t seeing any liveries for default aircraft from 2020 now in 2024 like the 787, 152, 172, DA40 NG, DA40 tDi, TBM930, Baron, Bonanza etc. Asobo have changed the aircraft so dramtically no-one has been able to work out how to get a livery working. Even once we got our head around the new file structure, these aircraft resist all attempts to show a livery.
You can usually get liveries for any default aircraft developed outside of Asobo working in 2024. But using the same methods on the other aircraft like the 787 produces nothing other than an all white livery. Why?
Any liveries for aircraft still in the old 2020 format but operating in 2024 are quite easy to convert.
Most livery creators believe that getting access to the source files (currently hidden or encrypted) will solve all the problems. But I have my doubts. Our best case scenario could be that every livery will have to be created again from nothing. The worst case scenario is that add-on liveries are a thing of the past.
The method Asobo use to create different liveries is to modify the 3d model. This represents a huge amount of work, and requires skills beyond the majority of livery creators. But it gives great performance benefits for lower end PCs and XBox. The method livery creators use is to modify the base textures. This is a 100 times less time consuming than modifying the 3d model, but looks just as good in most cases. But it is not the method of choice for Asobo, as they always have to consider performance limitations of XBox.
Asobo have provided zero help to livery creators, in spite of them being responsible for the huge library of free content that made MSFS 2020 such a success. Whether this was just an oversight or planned is anyone’s guess. Whatever the reason, it has resulted in no 3rd party liveries for certain aircraft in 2024.
