Grey Four-Engine Aircraft - Native Scenes and Display Models

OVERVIEW
A four-engine propeller-aircraft display subject with a high wing, tall tail, cockpit windows, engine nacelles, external tanks, thin aerial details and the existing landing-gear geometry. Native FBX and original OBJ each reopen as one surface mesh with 17,455 triangles. The illustration presents the complete assembled source in its retained upright pose. It is a static miniature subject, not a tested flying model or working mechanical kit.

APPEARANCE
The cover retains the supplied grey diffuse texture, dark nose and cockpit appearance, red wing/tail areas, markings and existing surface shapes. It explicitly connects the supplied PNG normal map for surface-lighting detail and uses a proposed matte display shader. Those shading choices do not add vertices, printed relief or new aircraft components. Fine lettering, panel lines and texture-normal details may not exist as raised geometry. Inspect the untextured mesh and slicer before expecting them in a physical print.

FORMATS AND EARLIER VARIANTS
The complete archive retains native FBX, MAX, original bare OBJ, separate MTL and all five original bitmap maps. Four previously published OBJ representations are independently preserved and reopened. All eight attached downloads remain available under new opaque filenames. The four earlier ZIPs are reconciled into equivalent complete packages containing the retained native data and display variants.

The earlier FBX numerical scene/animation payload and MAX non-asset streams match the preserved originals. All four earlier MTL libraries have the same numerical values and bind byte-identical map content as the original MTL. Only resource paths and nonessential labels change. Earlier unbound supplier imagery and preparation documents are replaced publicly by the current local-PC AI illustration and this English guide; originals remain preserved privately.

MATERIAL PATHS AND NATIVE PRESERVATION
The original OBJ has no mtllib or usemtl directives and remains a bare geometric representation. Its supplied MTL is retained separately with paths to the included diffuse image. Use the FBX for the bound textured scene; bare OBJ viewers may display neutral geometry. All five maps remain available, including auxiliary maps not automatically interpreted by every importer. Keep the linked resources together.

Original and renamed native scenes are independently compared for geometry, UV coordinates, material indices and transforms, including world matrices at frames 1, 125 and 250. One native action remains in FBX. MAX copies preserve all non-asset compound-document streams and legitimate notices. Native scripts were not executed and a 3ds Max GUI reopening is not claimed.

Untested source geometry. Confirm slicer units, manifoldness, intersecting surfaces and fine-feature thickness. The upright display OBJ is normalized for visualization; use full-resolution source geometry in the corrected package for fabrication checks. No verified physical scale, print settings, assembly fit or flight capability is claimed.

Prepared for display and download. No physical print has been certified.
