  "titleEn": "Urban transit bus",
  "description": "停留所や都市道路に配置する、二軸の低床型路線バスです。長い車体、二か所の閉じた乗客扉、広い窓、段差付きの後部床、座席、手すりと吊り手、運転席・操舵輪・計器、車軸と底部フレーム、後部サービスグリル、屋根上の空調外装を一式に造形しています。淡いアルファ透過ガラスをGLBに収録し、側窓と前面窓から実際の座席と車内が見えます。扉下部の暗色パネル・ミラー・灯火・行先表示欄は不透明です。屈折ガラス、内部エンジン、文字、人物、扉開閉・走行・操舵・空調動作は含みません。部品全体で一モデルです。 ゲーム・可視化向け。製造・構造設計・3Dプリント用途は未検証。 外接寸法（X×Y×Z）3.110 × 3.186 × 10.880 m、136,940三角形。単位m・Y-up、水平中央の接地用原点、最下点Y=0。部品ごとの重複UV0と単色PBR材質を収録し、画像テクスチャ・UV2・コライダー・LOD・リグ・動作は付属しません。静的表示用でUnity/VRChat実機検証は未実施。STLはm・Y-up座標の形状のみで色・材質・UV・階層を含みません。",
  "descriptionEn": "A two-axle low-floor-style transit bus for stops and urban road scenes. Its long body includes two closed passenger doorways, broad windows, a stepped rear floor, modeled passenger seats, handrails and hanging grips, driver seat with steering wheel and blank instruments, axles and underframe, rear service grille and rooftop HVAC exterior. Lightly tinted alpha-blended glazing is exported in the GLB, allowing genuine views of the included seats and cabin. Lower dark door panels, mirrors, lamps and the blank destination panel are opaque. No refractive-glass simulation, internal engine, lettering, people, door, driving, steering or HVAC behavior is included. All components form one complete model. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 3.110 × 3.186 × 10.880 m; 136,940 triangles. Metres, Y-up, horizontally centered placement origin with minimum Y=0, not an articulation or wall-mount pivot. Includes overlapping component UV0 and constant-color PBR materials, with no image textures, unique UV2, colliders, LOD, rig or runtime behavior. Static visualization only; Unity/VRChat editor and runtime tests have not been performed. STL uses metre-valued Y-up coordinates and contains geometry only, without color, materials, UVs or hierarchy.",
