Square-Pillar Hourglass (A103) is a nonfunctional static 3D exterior model. Its catalogue source names it “사각 기둥 모래시계 외장” and records 2,344 triangles and 16 parts. This listing covers visible geometry only, not a working object, fabrication instructions, or a mechanically accurate replica. The original archive is supplied with native Blender source, an exchange GLB, previews and source/QA material; check the package contents for the exact file set. The preferred exchange-file reference is Material/A103_Exterior.glb. The ORM red channel is constant 1, not baked ambient occlusion. Visual quality has not been independently reviewed, and external-engine compatibility, rigging, animation, LOD, collision, and game-readiness are not promised. AI disclosure: This original digital 3D asset was made with AI assistance. Its source files and previews are supplied for buyer inspection; no independent artistic or technical certification is claimed. 사각 기둥 모래시계 외장 | A103。非機能の静的3D外観モデルです。詳しい利用条件は同梱ライセンスをご確認ください。
