Between commissions, IXEG’s design lab pursued experimental concepts: a livery meant to visualize airflow and real-time aerodynamic feedback. They painted a translucent thermographic motif along the fuselage, and through augmented shader effects, they simulated trail vortices and pressure gradients as neon arcs. In practice flights, this livery revealed how the 737-300’s winglets and engine pylon interacted with crosswinds. Test pilots called it "the ghostline." It was an educational tool and a spectacle—passengers in the virtual cabin watched the vortex streamers from windows during demonstration flights to aeronautical students.
If you are new to the IXEG, installing liveries is straightforward but requires attention to folder structure: ixeg 737300 liveries
