  "description": "駐車場や高架下の入口に立つ、高さ制限の門型ゲートです。亜鉛めっきの2本の柱と上部の梁、柱の黄色と黒の帯、鎖で吊った黄黒の警告バー、柱脚のベースプレートを造形しています。制限高さの数字や注意文の文字、衝突時の揺れは含みません。幅約3.7m、警告バー下端は約2.45m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）3.950 × 2.925 × 0.350 m、4,692三角形。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 height-limit gantry for car park and underpass entrances. It models two galvanized uprights with a top beam, yellow-and-black bands on the uprights, a yellow-and-black warning bar hung on chains, and base plates. Clearance numerals and warning text, and swinging on impact, are not included. About 3.7 m wide; the warning bar underside is at about 2.45 m. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 3.950 × 2.925 × 0.350 m; 4,692 triangles. Metres, Y-up, horizontally centered placement origin with minimum Y=0, not an articulation or mounting 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.",
