# MeshyRigModelNode - ComfyUI Built-in Node Documentation

> Complete documentation for the MeshyRigModelNode 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/MeshyRigModelNode/en.md)

The Meshy: Rig Model node takes a 3D model task from Meshy and generates a rigged character model. It automatically creates a skeleton for the model, allowing it to be posed and animated. The node outputs the rigged model in both GLB and FBX file formats.

## Inputs

| Parameter       | Data Type | Required | Range       | Description                                                                                                                 |
| --------------- | --------- | -------- | ----------- | --------------------------------------------------------------------------------------------------------------------------- |
| `meshy_task_id` | STRING    | Yes      | N/A         | The unique task ID from a previous Meshy operation (e.g., text-to-3D or image-to-3D) that generated the model to be rigged. |
| `height_meters` | FLOAT     | Yes      | 0.1 to 15.0 | The approximate height of the character model in meters. This aids in scaling and rigging accuracy (default: 1.7).          |
| `texture_image` | IMAGE     | No       | N/A         | The model's UV-unwrapped base color texture image.                                                                          |

**Note:** The auto-rigging process is currently not suitable for untextured meshes, non-humanoid assets, or humanoid assets with unclear limb and body structure.

## Outputs

| Output Name   | Data Type | Description                                                                               |
| ------------- | --------- | ----------------------------------------------------------------------------------------- |
| `model_file`  | STRING    | A legacy output for backward compatibility, containing the filename of the GLB model.     |
| `rig_task_id` | STRING    | The unique task ID for this rigging operation, which can be used to reference the result. |
| `GLB`         | FILE3DGLB | The rigged 3D character model saved in the GLB file format.                               |
| `FBX`         | FILE3DFBX | The rigged 3D character model saved in the FBX file format.                               |
