# TripoTextToModelNode - ComfyUI Built-in Node Documentation

> This legacy node generates finished 3D models from a text description using Tripo's API.

This legacy node generates finished 3D models from a text description using Tripo's API. It waits for generation to complete and then returns the model file, optionally with textures and PBR materials. It is marked as deprecated and is kept for older workflows.

## Inputs

| `prompt`           | Text description of the 3D model to generate (multiline). This parameter is required and cannot be empty.                                                                                                                  | STRING    | Yes      | -                                         |
| `negative_prompt`  | Text description of what to avoid in the generated model (multiline). Up to 255 characters. Sent to the API only when non-empty.                                                                                           | STRING    | No       | Up to 255 characters                      |
| `model_version`    | Version of the Tripo model to use for generation (default: v3\_1\_20260211).                                                                                                                                               | COMBO     | No       | Multiple options available                |
| `style`            | No longer supported by Tripo and ignored. Kept for older workflows (default: "None").                                                                                                                                      | COMBO     | No       | Multiple options available                |
| `texture`          | Generate texture maps. Off returns bare geometry and ignores `pbr` (default: True).                                                                                                                                        | BOOLEAN   | No       | true / false                              |
| `pbr`              | PBR material maps (base color, metallic, roughness, normal). Requires `texture`; forced off when `texture` is off (default: True).                                                                                         | BOOLEAN   | No       | true / false                              |
| `image_seed`       | Seed used for the image generation stage (default: 42).                                                                                                                                                                    | INT       | No       | 0 to 2147483647                           |
| `model_seed`       | Seed used for the model generation stage (default: 42).                                                                                                                                                                    | INT       | No       | 0 to 2147483647                           |
| `texture_seed`     | Seed used for the texture generation stage (default: 42).                                                                                                                                                                  | INT       | No       | 0 to 2147483647                           |
| `texture_quality`  | Quality of the generated textures. detailed = HD textures, extreme = 8K Ultra textures (default: standard).                                                                                                                | COMBO     | No       | "standard"<br />"detailed"<br />"extreme" |
| `face_limit`       | Maximum face count. -1 lets Tripo pick adaptively (about 1.4M faces on v3.x standard, 2M on detailed). Tripo clamps silently: v2.5 at 500,000, quad meshes at 150,000. (default: -1)                                       | INT       | No       | -1 to 2000000                             |
| `quad`             | Quad mesh output. Tripo delivers quad meshes as FBX, so the result arrives on the FBX output and the GLB output stays empty. (default: False)                                                                              | BOOLEAN   | No       | true / false                              |
| `geometry_quality` | Quality of the generated geometry (default: standard).                                                                                                                                                                     | COMBO     | No       | "standard"<br />"detailed"                |
| `smart_low_poly`   | Low-poly mesh with clean, hand-crafted style topology (500-20,000 faces, quad 500-10,000). Best for simple subjects; complex ones may fail. (default: False)                                                               | BOOLEAN   | No       | true / false                              |
| `auto_size`        | Scale textured models to their real-world size in meters. Tripo stores the size as the model's scene transform and bakes it in when the model is converted, rigged or retargeted; ignored without texture. (default: True) | BOOLEAN   | No       | true / false                              |

**Notes:**

* This node is deprecated and marked as a legacy node. It is kept for backward compatibility with older workflows.
* The `prompt` parameter is mandatory: an empty prompt causes the node to raise an error.
* `pbr` requires `texture`. When `texture` is off, the node forces `pbr` to off and ignores its value. `auto_size` also has no effect without `texture`.
* When `smart_low_poly` is enabled and `face_limit` is set to a value other than -1, the face limit must be between 500 and 20,000 for triangle output, or between 500 and 10,000 when `quad` is enabled; otherwise the node raises an error.
* When `quad` is enabled, the generated quad mesh is delivered as FBX, so the FBX output is populated and the GLB output stays empty.
* The `style` parameter is accepted but ignored.
