What is Hunyuan3D-Part
Hunyuan3D-Part is launched by Tencent3D generation model, composed of P3 – SAM and X – Part, it achieves high-precision, controllable component-based 3D generation for the first time, supporting automatic generation of 50+ components. Users can first use Hunyuan3D 2.5 or 3.0 to generate the overall Mesh, then P3 – SAM performs automatic and precise component segmentation, and X – Part decomposes it into independent parts, outputting high-fidelity, structurally consistent part geometry while maintaining flexible controllability. It has wide applications in game modeling, 3D printing, and other fields, such as splitting a car model into the body and wheels, facilitating binding rolling logic in games or step-by-step production in 3D printing. Models generated by Hunyuan3D – Part have high precision, are editable, and have reasonable structure, making models easier to edit, produce, and apply. It can be accessed viaTencent Hunyuan3Dcreative engine for free.
