  "description": "消防署の車庫前や都市の緊急車両シーンに配置する、文字のない二軸ポンプ車です。乗員用の長いキャブ、前後二列の座席、操舵輪と計器、側面機材シャッター、露出したポンプ操作盤・固定指針の計器・弁ハンドルと接続口、屋根上の折り畳みホース束と積載はしご、後部ホースリール、ステップと底部フレームを一式に造形しています。キャブ窓はGLBの淡いアルファ透過材質で、実際の内装を見通せます。灯火とミラーは不透明で消灯状態、機材室とタンクの内部は省略しています。屈折ガラス、文字、人物、放水・油圧・扉開閉・走行・操舵動作、実車の性能や安全性の検証は含みません。全体で一モデルです。 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）3.070 × 3.310 × 7.760 m、152,156三角形。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": "An unlettered two-axle pumper truck for station forecourts and urban emergency-vehicle scenes. A long crew cab with two seat rows, steering and blank instruments is paired with equipment shutters, an exposed pump panel with fixed-needle gauges, valve handwheels and capped couplings, top folded hose stacks and a stowed ladder, rear hose reel, steps and underframe. Lightly tinted alpha-blended cab glazing reveals actual included interior geometry. Lamps and mirrors are opaque and inactive; equipment-bay and tank internals are omitted. No refractive-glass simulation, lettering, people, water, hydraulic, door, driving or steering behavior, real-vehicle performance or safety validation is included. All components form one complete model. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 3.070 × 3.310 × 7.760 m; 152,156 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.",
