# Load3DAdvanced - ComfyUI Built-in Node Documentation

> Complete documentation for the Load3DAdvanced node in ComfyUI. Learn its inputs, outputs, parameters and usage.

This node loads a 3D model file from your ComfyUI input directory and provides the model data along with camera and viewport information. It supports common 3D file formats and allows you to specify the output image dimensions for rendering.

## Inputs

| Parameter        | Description                                                                            | Data Type | Required | Range                                                              |
| ---------------- | -------------------------------------------------------------------------------------- | --------- | -------- | ------------------------------------------------------------------ |
| `model_file`     | The 3D model file to load. Select "none" to skip loading a model.                      | STRING    | Yes      | `"none"`<br />List of available 3D files in the input/3d directory |
| `viewport_state` | The current viewport state containing camera and model information from the 3D viewer. | LOAD3D    | Yes      | -                                                                  |
| `width`          | The width of the output image in pixels (default: 1024)                                | INT       | Yes      | Min: 1<br />Max: 4096<br />Step: 1                                 |
| `height`         | The height of the output image in pixels (default: 1024)                               | INT       | Yes      | Min: 1<br />Max: 4096<br />Step: 1                                 |

**Notes on Parameters:**

* The `model_file` parameter only shows files with the following extensions: .gltf, .glb, .obj, .fbx, .stl
* Files must be placed in the `input/3d` directory of your ComfyUI installation
* If `model_file` is set to "none", no 3D model data will be loaded (the output `model_3d` will be empty)

## Outputs

| Output Name     | Description                                                      | Data Type       |
| --------------- | ---------------------------------------------------------------- | --------------- |
| `model_3d`      | The loaded 3D model data, or empty if no model file was selected | FILE3DANY       |
| `model_3d_info` | Information about the loaded 3D model from the viewport state    | LOAD3DMODELINFO |
| `camera_info`   | Camera information from the viewport state                       | LOAD3DCAMERA    |
| `width`         | The specified output image width                                 | INT             |
| `height`        | The specified output image height                                | INT             |
