# TripoRefineNode - ComfyUI Built-in Node Documentation

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

The TripoRefineNode refines draft 3D models created specifically by Tripo v1.4 models. It takes a model task ID and processes it through the Tripo API to generate an improved version of the model. This node is designed to work exclusively with draft models produced by Tripo v1.4 models.

## Inputs

| Parameter       | Data Type       | Required | Range | Description                |
| --------------- | --------------- | -------- | ----- | -------------------------- |
| `model_task_id` | MODEL\_TASK\_ID | Yes      | -     | Must be a v1.4 Tripo model |

**Note:** This node only accepts draft models created by Tripo v1.4 models. Using models from other versions may result in errors.

## Outputs

| Output Name     | Data Type       | Description                                                                       |
| --------------- | --------------- | --------------------------------------------------------------------------------- |
| `model_file`    | STRING          | The file path or reference to the refined model (for backward compatibility only) |
| `model task_id` | MODEL\_TASK\_ID | The task identifier for the refined model operation                               |
| `GLB`           | FILE3DGLB       | The refined 3D model in GLB format                                                |
