This node uses Tencent's Hunyuan3D Pro API to generate a 3D model from one or more input images. It processes the images, sends them to the API, and returns the generated 3D model files in GLB and OBJ formats.

## Inputs

| Parameter                    | Data Type    | Required | Range                                         | Description                                                                                                                                                         |

| `generate_type`              | DYNAMICCOMBO | Yes      | `"Normal"`<br />`"LowPoly"`<br />`"Geometry"` | The type of 3D model to generate. Selecting an option reveals additional related parameters.                                                                        |

**Note:** All input images must have a minimum width and height of 128 pixels.
