paper envelope 3d model

Photorealistic 3D model of a paper envelope BODY ONLY. This is a partial asset. Missing parts are intentional. Do NOT add or reconstruct a top flap. Real-world scale: 22 cm width, 11 cm height, 0.2 cm paper thickness. Thin folded paper geometry forming the main pocket, with realistic side and bottom overlaps only. Slight curvature along fold lines, not perfectly flat. Clean quad-based topology, real-time optimized 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. Single mesh only. Centered at world origin. Photorealistic stationery look, elegant and romantic, not stylized. No flap, no text, no logos, no patterns.
