Hunyuan3D-2.1
Hunyuan3D-2.1 separates shape generation from physically based texture generation. The release includes model weights and training code for adaptation.
Model design and access
The texture stage predicts material properties for lighting interactions instead of only an RGB surface image. Shape and painting can be run separately. The figures in the documentation describe its reference pipeline, not every mesh size or inference configuration.Hunyuan3D-2.1 official model documentation
Practical use
Practical guidance. Inspect topology, unseen surfaces and material response in the target renderer. A visually convincing preview can still require mesh cleanup, UV work or a simpler geometry budget for a game.
