Hunyuan 3D 2.1

Hunyuan 3D 2.1 prioritizes the balance of high-quality geometry and realistic surface behavior through a physics-grounded material pipeline. It excels at capturing fine details like curves and edges from a single reference image, producing cleaner silhouettes than the 2.0 series. The model generates true PBR textures—including metallic and roughness maps—that accurately simulate how light interacts with materials like leather or metal.
