Flag decals

[Greathouse]

Seen a few screenclips on kspbuils and ect of rockets and planes displaying country flags and decals like we could in ksp 1, i may be overlooking bur havnt seen a way or mod to add these im wondering how these people were able to do so

My guess would be mostly using procedural wings to create decals, like @The Space Peacock's competition-winning Vulcan recreation: https://kspbuilds.com/build/Vulcan-Centaur-&-Peregrine-Lander
