I don’t use the megapack because it consumes FPS and because it is limited to Asobo planes.
I use IVAO liveries (x-csl) which, however, must be changed.
It’s a bit of a hard job but now that I’ve figured out how to organize them, I’m starting to feel better.
Above all, I avoid touching the ASOBO files because there is a risk that after an update you will lose your work. I only work in the Community folder.
