> Complete documentation for the TencentTextToModelNode node in ComfyUI. Learn its inputs, outputs, parameters and usage.

> This documentation was AI-generated. If you find any errors or have suggestions for improvement, please feel free to contribute! [Edit on GitHub](https://github.com/Comfy-Org/embedded-docs/blob/main/comfyui_embedded_docs/docs/TencentTextToModelNode/en.md)

This node uses Tencent's Hunyuan3D Pro API to generate a 3D model from a text description. It sends a request to create a generation task, polls for the result, and downloads the final model files in GLB and OBJ formats.

## Inputs

| Parameter       | Data Type    | Required | Range                                         | Description                                                                                                                                                                                                                                                                                                                                                                                              |
| --------------- | ------------ | -------- | --------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `model`         | COMBO        | Yes      | `"3.0"`<br />`"3.1"`                          | The version of the Hunyuan3D model to use. The LowPoly option is unavailable for the `3.1` model.                                                                                                                                                                                                                                                                                                        |
| `prompt`        | STRING       | Yes      | -                                             | The text description of the 3D model to generate. Supports up to 1024 characters.                                                                                                                                                                                                                                                                                                                        |
| `face_count`    | INT          | Yes      | 40000 - 1500000                               | The target number of faces for the generated 3D model. Default: 500000.                                                                                                                                                                                                                                                                                                                                  |
| `generate_type` | DYNAMICCOMBO | Yes      | `"Normal"`<br />`"LowPoly"`<br />`"Geometry"` | The type of 3D model to generate. The available options and their associated parameters are:<br />- **Normal**: Generates a standard model. Includes a `pbr` parameter (default: `False`).<br />- **LowPoly**: Generates a low-polygon model. Includes `polygon_type` (`"triangle"` or `"quadrilateral"`) and `pbr` (default: `False`) parameters.<br />- **Geometry**: Generates a geometry-only model. |
| `seed`          | INT          | No       | 0 - 2147483647                                | A seed value for the generation. Results are non-deterministic regardless of seed. Setting a new seed controls whether the node should re-run. Default: 0.                                                                                                                                                                                                                                               |

**Note:** The `generate_type` parameter is dynamic. Selecting `"LowPoly"` will reveal additional inputs for `polygon_type` and `pbr`. Selecting `"Normal"` will reveal an input for `pbr`. Selecting `"Geometry"` will not reveal any additional inputs.

**Constraint:** The `"LowPoly"` generate type cannot be used with the `"3.1"` model.
