# MeshyImageToModelNode - ComfyUI Built-in Node Documentation

> The Meshy: Image to Model node uses the Meshy API to generate a 3D model from a single input image.

The Meshy: Image to Model node uses the Meshy API to generate a 3D model from a single input image. It uploads your image, submits a processing task, and returns the generated 3D model files (GLB and FBX) along with the task ID for reference.

## Inputs

| Parameter | Description | Data Type | Required | Range |
| - | - | - | - | - |
| `model` | Specifies the AI model version to use for generation. | COMBO | Yes | `"meshy-7.1"`<br />`"meshy-7"`<br />`"meshy-6"`<br />`"latest"` |
| `image` | The input image to convert into a 3D model. | IMAGE | Yes | - |
| `should_remesh` | When set to `"false"`, returns an unprocessed triangular mesh. | DYNAMIC\_COMBO | Yes | `"true"`<br />`"false"` |
| `topology` | The target polygon topology for the remeshed model. This input is only available when `should_remesh` is set to `"true"`. | COMBO | No\* | `"triangle"`<br />`"quad"` |
| `target_polycount` | The target number of polygons for the remeshed model. This input is only available when `should_remesh` is set to `"true"`. Default: 300000. | INT | No\* | 100 - 300000 |
| `symmetry_mode` | Controls the symmetry applied to the generated 3D model. | COMBO | Yes | `"auto"`<br />`"on"`<br />`"off"` |
| `should_texture` | Determines whether textures are generated. Setting it to `"false"` skips the texture phase and returns a mesh without textures. | DYNAMIC\_COMBO | Yes | `"true"`<br />`"false"` |
| `enable_pbr` | Generate PBR Maps (metallic, roughness, normal) in addition to the base color. This input is only available when `should_texture` is set to `"true"`. Default: `False`. | BOOLEAN | No\* | - |
| `texture_prompt` | Provide a text prompt to guide the texturing process. Maximum 600 characters. Cannot be used at the same time as `texture_image`. This input is only available when `should_texture` is set to `"true"`. Default: empty string. | STRING | No\* | - |
| `texture_image` | Only one of `texture_image` or `texture_prompt` may be used at the same time. This input is only available when `should_texture` is set to `"true"`. | IMAGE | No\* | - |
| `texture_resolution` | Base color texture resolution. Higher resolutions capture more surface detail. This input is only available when `should_texture` is set to `"true"`. | COMBO | No\* | `"2k"`<br />`"4k"`<br />`"8k"` |
| `pose_mode` | Specify the pose mode for the generated model. This is an advanced parameter. | COMBO | Yes | `""` (empty)<br />`"A-pose"`<br />`"T-pose"` |
| `seed` | Seed controls whether the node should re-run; results are non-deterministic regardless of seed. Default: 0. | INT | Yes | 0 - 2147483647 |
| `ultra_mode` | Run an extra refinement pass for higher-fidelity geometry with finer surface detail. Default: `False`. | BOOLEAN | Yes | - |
| `ultra_resolution` | Resolution of the ultra pass: `"2k"` runs it at 2048³, `"4k"` at 4096³ for the finest surface detail. 4k requires the `"meshy-7.1"` or `"latest"` model. Used only when `ultra_mode` is enabled (default: `"2k"`). | COMBO | No | `"2k"`<br />`"4k"` |

**Note on Parameter Constraints:**

* The `topology` and `target_polycount` inputs are only available when `should_remesh` is set to `"true"`.
* The `enable_pbr`, `texture_prompt`, `texture_image`, and `texture_resolution` inputs are only available when `should_texture` is set to `"true"`.
* When `should_texture` is set to `"true"`, `texture_prompt` and `texture_image` cannot be used at the same time. If both are provided, the node raises an error.
* `texture_prompt` has a maximum length of 600 characters.
* When `ultra_mode` is enabled, the `model` parameter must be set to `"meshy-7.1"`, `"meshy-7"` or `"latest"`; any other model raises an error. With `"meshy-7"` the ultra pass always runs at 2048³, and the `"4k"` ultra resolution requires `"meshy-7.1"` or `"latest"`.

## Outputs

| Output Name | Description | Data Type |
| - | - | - |
| `model_file` | The filename of the generated GLB model. Maintained for backward compatibility only. | STRING |
| `meshy_task_id` | The unique identifier for the Meshy API task, which can be used for reference or troubleshooting. | MESHY\_TASK\_ID |
| `GLB` | The generated 3D model in the GLB file format. | FILE3DGLB |
| `FBX` | The generated 3D model in the FBX file format. | FILE3DFBX |
