# Save3DAdvanced - ComfyUI Built-in Node Documentation

> Complete documentation for the Save3DAdvanced node in ComfyUI. Learn its inputs, outputs, parameters and usage.

This node saves a 3D model to your ComfyUI output directory and provides advanced preview capabilities. It allows you to specify the output filename, preview dimensions, and optionally pass camera and model information for an enhanced 3D viewer experience.

## Inputs

| Parameter         | Description                                                                                                         | Data Type       | Required | Range                                            |
