| ### ☯️ *Hunyuan3D Part** | |
| - Pipeline of our image to 3D part generation. It contains two key components, P3-SAM and X-Part. The holistic mesh is fed to part detection module P3-SAM to obtain the semantic features, part segmentations and part bounding boxes. Then X-Part generate the complete parts. | |

| #### **Notice** | |
| - **The current release is a light version of X-Part**. The full-blood version is available on [](https://3d.hunyuan.tencent.com/studio). | |
| - For X-Part, we recommend using scanned or AI-generated meshes (e.g., from Hunyuan3D V2.5 or V3.0) as input. | |
| - P3-SAM can handle any input mesh. | |
