DCdesigns F15D NASA improvement (justinparcher's MOD)

This add-on enhances the existing F-15 NASA paint by justinparcher, requiring his original mod for installation. Key improvements include texture corrections on the exhaust duct and fuselage, along with a polished gloss finish. Additional refinements to the cockpit visibility and wing pylons, as well as other detailing, complement the original design without detracting from it.
