# Preview 3D (Advanced)

This node provides an advanced 3D model preview with camera and model information output. It saves the 3D model to a temporary file and displays it in the UI, while also passing through the model data, camera information, and viewport dimensions for further processing downstream.

## Inputs

| Parameter | Description | Data Type | Required | Range |
|-----------|-------------|-----------|----------|-------|
| `model_3d` | 3D model file from an upstream 3D node. | FILE3D | Yes | GLB, GLTF, FBX, OBJ, STL, USDZ, or any supported 3D format |
| `model_3d_info` | Optional model information metadata. | LOAD3DMODELINFO | No | - |
| `viewport_state` | The current viewport state containing camera and model information. | LOAD3D | Yes | - |
| `camera_info` | Optional camera configuration for the 3D view. | LOAD3DCAMERA | No | - |
| `width` | The width of the preview in pixels. | INT | Yes | 1 to 4096 (default: 1024) |
| `height` | The height of the preview in pixels. | INT | Yes | 1 to 4096 (default: 1024) |

## Outputs

| Output Name | Description | Data Type |
|-------------|-------------|-----------|
| `model_3d` | The 3D model file passed through from the input. | FILE3D |
| `model_3d_info` | Model information metadata, either from the input or from the viewport state. | LOAD3DMODELINFO |
| `camera_info` | Camera configuration, either from the input or from the viewport state. | LOAD3DCAMERA |
| `width` | The width of the preview in pixels. | INT |
| `height` | The height of the preview in pixels. | INT |
