  "description": "住宅の敷地境界に多い、5段のコンクリートブロック塀と上部のアルミ縦格子フェンスです。1段ごとに半個ずらしたブロック、目地、笠木、フェンスの柱・上下の横材・縦格子を造形しています。長さ約2.4mの1区画で、控え壁・鉄筋・基礎の内部、構造的な安全性の検証は含みません。 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）2.420 × 1.860 × 0.150 m、7,356三角形。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 five-course concrete block wall topped by an aluminium picket fence, common on residential boundaries. It models half-offset blocks per course, mortar joints, coping, fence posts, top and bottom rails and pickets. One section about 2.4 m long; buttresses, reinforcement, footing internals and structural safety verification are not included. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 2.420 × 1.860 × 0.150 m; 7,356 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.",
