What's new in Hunyuan3D 3.1
Precision-engineered for production 3D workflows
8-View Reconstruction
Expanded multi-view input with top, bottom, left_front, and right_front angles on top of the standard four. More reference views means more accurate 3D reconstruction.
Watertight Meshes
Sealed, manifold geometry with zero holes or non-manifold edges. Models are immediately ready for 3D printing and boolean operations without manual repair.
Clean Quad Topology
Optimized topology generation produces clean quad-dominant meshes. Better edge flow at joints, limbs, and mechanical parts for animation and subdivision.
Smart UV Unwrapping
Reduced stretching and fewer seams in UV maps. Textures project accurately across the surface for consistent material appearance.
Improved Color Accuracy
Better handling of lighting interference during texture baking. More faithful color reproduction in albedo maps and physically grounded PBR channels.
Production-Ready Output
Configurable face count from 40K to 1.5M polygons. Choose triangle or quad topology. Models fit directly into game engines, CAD tools, and print slicers.
