Asset: Modern mid-size four-door family saloon / sedan (`family-sedan-g4.glb`) built from scratch in Blender 5.2 to Forge Garage contract v2 (4.82 m long, 1.86 m wide, 1.45 m high, 2.80 m wheelbase, +Z front, +Y up, +X left, tyres on y=0) with full exterior trim, wrap-around lamps, 5-twin-spoke wheels with brake discs/calipers, and full interior.
Triangle count: 90,202 triangles across 6 mesh nodes (`Body`, `Wheel_FL`, `Wheel_FR`, `Wheel_RL`, `Wheel_RR`, `SteeringWheel`) and 8 empty nodes (`Seat_Driver`, `Door_L`, `Door_R`, `Exhaust`, `Light_Head_L`, `Light_Head_R`, `Light_Tail_L`, `Light_Tail_R`).
Materials: 6 materials (`Paint` with neutral near-white baked grime texture, `baseColorFactor` `[0.02, 0.05, 0.16, 1.0]`, and `KHR_materials_clearcoat` 1.0 / roughness 0.05; `Trim`; `Rubber`; `Interior`; `Glass` with `alphaMode: BLEND`; `Lamps` with emissive headlights, taillights, and amber indicators).
Texture sizes: Cycles-baked textures at 1024x1024 px for base colour, normal, and lamp emission maps, and 512x512 px for packed ORM (occlusion/roughness/metallic) maps; total binary GLB size is 8.40 MB.
Poly Haven IDs (CC0 1k JPG `diff`, `nor_gl`, `arm`): `metal_plate_02`, `rusty_metal_03`, `rubberized_track`, `fabric_leather_02`.
Differences from reference sheet: The front hood-to-grille brow transition is slightly crisper than the concept illustration, and underbody suspension arms are omitted to stay within the 50k-100k triangle budget.
