  "description": "歩道や駐車場の保守シーン用の除雪機。前開きの曲面ハウジング、左右の螺旋オーガ、空洞の排雪筒、駆動輪、操作部を造形。雪、内部インペラ、燃料・エンジン内部、除雪・走行・可動は含まず、実機安全や性能を保証しません。 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）0.797 × 1.091 × 1.317 m、19,240三角形。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 snow-clearing prop for sidewalks and parking-area maintenance scenes. The open-front curved bucket exposes two helical augers, with an empty discharge chute, treaded drive wheels and operator controls. Snow, internal impeller, fuel and engine internals, snow-clearing, driving and articulation are absent; no real equipment safety or performance is warranted. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 0.797 × 1.091 × 1.317 m; 19,240 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.",
