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" 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 Max: 4096 Step: 1
height	The height of the output image in pixels (default: 1024)	INT	Yes	Min: 1 Max: 4096 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
