The IXEG 737-300 (specifically the "Classic Plus" for X-Plane 12) remains one of the most beloved "Classic" jet simulations, and its livery ecosystem is a major part of that longevity. The Official Experience

The team’s methods grew more sophisticated. Using photogrammetry and microdetail normal maps, they layered paint textures that responded to lighting, salt, and oil. Rivet shadows were not merely painted—they were mapped so specular highlights struck realistically across panel lines. The IXEG devs implemented a "fatigue shader" that subtly altered reflectivity where sun and hydraulic fluid would erode lacquer first. Pilots who flew long-haul sessions began to notice seasonal shifts: the same fuselage would read as bright and crisp in simulated spring, then dulled and streaked after months of simulated operations. Marcus liked to joke that their liveries had "circadian paint." The IXEG devs implemented a "fatigue shader" that
Updates and Fixes: Many high-quality liveries, like the SATA International 90's pack, have been updated to version 2.0 to fix initial graphical errors and add cockpit interior textures. IXEG 737-300 Frontier Airlines Fleet Package - X-Plane.org
