paper sheet 3d model

Create a highly detailed 3D model of a standard A4-sized sheet of paper (210 mm x 297 mm) that is designed to be bendable and wrinkleable. The model should feature a thin, flexible mesh with enough geometric subdivisions to allow realistic deformation—such as curling, folding, and crumpling—without losing surface integrity. The paper material should have a subtle matte finish with a slight microfiber texture, off-white color, and soft, slightly rounded edges to mimic real paper. Include minimal specular reflection and a faint translucency when backlit. The base pose can be flat or slightly curved to suggest flexibility, but the mesh must be optimized for cloth simulation or manual posing to achieve wrinkles and bends. Optionally, add a subtle grain direction or watermark for realism."
