Obviously, this would be an amazing feature to have in IF. However, their are a few conflicts I believe that could prevent this from happening.
FDS is a relatively small team and to build/ design thousands and thousands of airports/ terminals around the world would be very hard and almost unrealistic
A lot of devices would struggle to run this. Sure the iPad Pro’s and iPhone X’s would likely have no problem but older, less powerful devices I could defenitely see having an issue with this
To sum up, 3D buildings would be awesome in IF, but I just think an a330 rework or taxiway lights is a lot more likely…
