  "description": "道路の入口に立つ、車両進入禁止を示す丸い規制標識と支柱です。赤い反射面に白い横棒、アルミ板の巻き縁と裏面補強材、支柱への締付けバンドとボルト、頭部キャップを造形しています。補助標識・文字・規制時間の表示、地中基礎は含みません。 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）0.608 × 3.220 × 0.091 m、4,524三角形。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 round no-entry regulatory road sign on a galvanized pole. It models the red retroreflective face with a white horizontal bar, rolled aluminium rim, rear stiffening channels, pole clamp bands and bolt blocks, and a pole cap. Supplementary plates, lettering, time restrictions and the buried foundation are not included. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 0.608 × 3.220 × 0.091 m; 4,524 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.",
