  "description": "建設現場の荷役場面に置く打設用ホッパー外観。厚みのある開いた受け槽、脚付き支持枠、持上げ枠と吊り環、閉じた排出ゲート・ガイド・レバーを造形。ミキサーではなく、材料を受けて排出する容器の静的プロップです。コンクリート・クレーン・吊り索や排出動作はなく、揚重・耐荷重・打設性能や施工安全は未検証。 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）0.979 × 1.719 × 0.999 m、7,676三角形。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 pouring-skip exterior for construction lifting scenes, with a thick open hopper, footed support cage, lifting bail/eye, closed discharge gate, guides and lever. Unlike a mixer, this static prop represents a receiving and dispensing container. Concrete, crane, lifting sling and discharge behavior are absent; lifting, load, pouring performance and construction safety are unvalidated. For games and visualization; not validated for manufacture, structural engineering or 3D printing. Bounding dimensions (X×Y×Z): 0.979 × 1.719 × 0.999 m; 7,676 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.",
