paper envelope 3d model

Photorealistic 3D model of a paper envelope body only (main pocket, no top flap). Real-world scale: 22 cm width, 11 cm height, 0.2 cm paper thickness. Thin folded paper geometry with realistic side and bottom overlaps. Slight curvature along fold lines, not perfectly flat. Clean quad-based topology, optimized for real-time use under 3k polygons. Matte paper PBR material, soft blush pink / warm white Valentine color. Visible paper fibers, subtle roughness variation, fine normal map. Zero metallic, medium-high roughness. Photorealistic stationery look, elegant and romantic, not cartoon or stylized. Single object, centered at world origin, correct real-world scale. No top flap, no text, no logos, no patterns.
