White Utility Helicopter - Native Scenes and Display Models

OVERVIEW
A complete utility-helicopter display model with the supplied main rotor, tail rotor, glazed cockpit, detailed fuselage, side equipment, tail boom and wheel undercarriage. The proposed finished miniature retains the supplied white United Nations livery textures and existing technical markings. The illustration uses the actual seven-mesh FBX surface arrangement, upright with rotors above the wheel-supported fuselage. It is not a photograph of a physically printed or flight-tested model.

FORMATS AND SOURCE REPRESENTATIONS
The package retains native FBX and MAX, the OBJ with a documented replacement MTL, all twenty-one supplied bitmap-map resources and both previously published OBJ alternatives. The FBX independently reopens with seven surface meshes and 366,085 triangles. The original OBJ independently reopens with ten mesh objects and 365,489 triangles; three objects are non-surface helpers. Those helpers remain in the native download. The two native representations have different triangulation and each is retained and checked against its own source. The compact display concentrates on actual surface geometry. Object counts do not establish a kit of independently printable parts.

TEXTURES AND DOCUMENTED DERIVATIVES
Three diffuse bitmap bindings were identified in the FBX. All twenty-one supplied colour, normal and auxiliary maps are retained byte for byte, including maps not automatically connected by the inspected importer. The authored OBJ material library is absent from both original source-folder aliases. A neutral MTL generated during an earlier recovery is preserved as an explicitly identified derivative, not recovered original shading. The unavailable vendor UV_Checker.png is represented by a documented generated diagnostic checker, not an original texture, livery map or missing supplied asset. The recovery notes and inventory are included in updated English documentation.

NATIVE PRESERVATION
FBX numerical geometry, UV data, material indices, hierarchy and transforms were compared after opaque resource relinking and independent reopening. MAX geometry, scene, material, script and source-notice streams remain unchanged outside the typed asset-path registry. Supplied texture references are relinked to actual included files. Native scripts were not executed, and a 3ds Max GUI reopening is not claimed. Legitimate native metadata, exporter notices and necessary technical identifiers remain. Source reference imagery is replaced in the public package by the new local-PC AI illustration; original corpus files remain unchanged.

SCALE AND DIMENSIONS
No reliable source physical scale or fabrication units have been verified. The formats use markedly different coordinate magnitudes, and non-surface helpers can distort an overall bounding box. Measure the actual fuselage and rotor envelope before choosing units, combining formats or resizing. For a uniform change, divide the target measurement by the current measurement and multiply by 100. The browser display is normalized only for viewing. Recheck blade thickness, landing-gear struts, glazing edges and clearance after every scale change.

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.
