This is a realistic 3D model of a standard STOP sign, complete with post and mounting fasteners.
The model includes two texture sets: one representing a new sign, and the other an old, weathered version.

Model Overview
        Polygon count: 332
        Vertex count: 381
        Objects in the scene: 3
                    STOP_Sign_Panel: 14 polygons / 16 vertices
                    STOP_Sign_Post: 28 polygons / 26 vertices
                    STOP_Sign_Fasteners: 290 polygons / 339 vertices
        Scale: Real-world scale (metric, millimeters).
        Pivot Point:
                    The sign panel and fasteners have their pivot at the base center of the panel, allowing easy rotation, detachment, or reuse.
                    The post pivot is placed at the bottom center, aligned with world origin.
        Scene contents: Only model objects are present — no camera, no lighting, and no environment.
        Model Dimensions
                    Total height: 2 850 mm
                    Sign panel: 750 × 750 mm (octagonal), 5 mm thick.
                                  Real-world sign panel thickness is typically 2 mm; this model uses 5 mm for better visual readability in 3D.
                    Post: 38 mm × 38 mm, 2 850 mm tall.
                    The Sign_Post does not include physically modeled holes; instead, they are represented using a Normal map to preserve a low polygon count.

Textures and Materials
        All textures are included in a ZIP archive named Textures, inside which there is a single folder (also named Textures) containing two subfolders:
                    NEW – clean, freshly installed sign;
                    OLD – weathered and aged version.
        Each folder includes five PBR texture maps: BaseColor, Normal, Roughness, Metallic, AO (with different prefixes, for example, STOP_Sign_New_BaseColor and STOP_Sign_Old_BaseColor for two variations of texture).
        In the .max and .fbx files, the material is named STOP_Sign, but no textures are assigned.
        For Blender, two separate .blend files contain the same model but different materials and texture assignments.
                    In STOP_Sign_New.blend, the material is named STOP_Sign_New and uses textures from the NEW folder.
                    In STOP_Sign_Old.blend, the material is named STOP_Sign_Old and uses textures from the OLD folder.
        Resolution: 2K (2048 × 2048).
        Format: PNG.
        All texture maps were created using Adobe Substance 3D Painter 8.2.0.

Preview Renders
        Rendered in Marmoset Toolbag.
        Wireframe views from 3ds Max are included for topology inspection.
