The TripoRefineNode refines draft 3D models created specifically by v1.4 Tripo 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             |
| `auth_token`    | AUTH\_TOKEN\_COMFY\_ORG | No       | -     | Authentication token for Comfy.org API |
| `comfy_api_key` | API\_KEY\_COMFY\_ORG    | No       | -     | API key for Comfy.org services         |
| `unique_id`     | UNIQUE\_ID              | No       | -     | Unique identifier for the operation    |
