  "description": "片側交互通行の工事区間に置く、トレーラー式の仮設信号機です。黄色いシャシーと泥よけ、2輪の車輪、牽引棒と連結器、四隅のジャッキと接地パッド、バッテリー・制御箱、伸縮マスト、背板付き3灯の灯器とひさしを造形しています。赤レンズが点灯（発光材質）、黄・青は消灯状態で、信号の切替、走行、配線、注意書きの文字は含みません。 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）2.060 × 3.134 × 1.160 m、6,976三角形。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 trailer-mounted temporary traffic signal for alternating one-lane roadworks. It models the yellow chassis and mudguards, two wheels, drawbar and coupler, corner jacks with pads, battery and controller box, telescopic mast, and a three-lamp head with backplate and visors. The red lens is lit with an emissive material and the amber and green lenses are unlit; signal switching, towing, wiring and warning lettering are not included. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 2.060 × 3.134 × 1.160 m; 6,976 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.",
