Preview3DAdvanced - ComfyUI Built-in Node Documentation

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
