Save3DAdvanced - ComfyUI Built-in Node Documentation - ComfyUI

Saves a 3D model to a file in the ComfyUI output directory and produces a preview of the saved scene. It also passes the 3D model, its placement in the scene, camera information, and viewport dimensions through to downstream nodes. When model placement or camera information are not connected, the node uses the values stored in the viewport state.

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 Any
`filename_prefix`	Prefix used for the saved file name (default: “3d/ComfyUI”).	STRING	Yes	Free text
`viewport_state`	Viewport state containing camera and model placement information, typically from a Load 3D node.	LOAD3D	Yes	-
`model_3d_info`	Placement of each model in the scene: position, rotation, and scale (Y-up world space). Overrides the model placement stored in `viewport_state` when connected.	LOAD3DMODELINFO	No	-
`camera_info`	Viewport camera information: position, look-at target, zoom, and type. Overrides the camera information stored in `viewport_state` when connected.	LOAD3DCAMERA	No	-
`width`	Render width of the viewport in pixels (default: 1024).	INT	Yes	1 to 4096
`height`	Render height of the viewport in pixels (default: 1024).	INT	Yes	1 to 4096

Note: model_3d_info and camera_info are optional. When either input is not connected, the node falls back to the corresponding values stored in viewport_state.

Outputs

Output Name	Description	Data Type
`model_3d`	The 3D model file passed through from the input.	FILE3D
`model_3d_info`	Placement of each model in the scene: position, rotation, and scale (Y-up world space).	LOAD3DMODELINFO
`camera_info`	Viewport camera information: position, look-at target, zoom, and type.	LOAD3DCAMERA
`width`	The render width value passed through from the input.	INT
`height`	The render height value passed through from the input.	INT
