Save3DAdvanced - ComfyUI Built-in Node Documentation - ComfyUI

This node saves a 3D model to a file in the ComfyUI output directory, with advanced control over the output dimensions and camera/viewport settings. It also passes through the 3D model, model information, camera information, and dimensions for downstream nodes.

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 for the saved file name (default: “3d/ComfyUI”).	STRING	Yes	Free text
`viewport_state`	Viewport state from a Load 3D node, containing camera and model information.	LOAD3D	Yes	-
`model_3d_info`	Optional 3D model information to override the viewport state.	LOAD3DMODELINFO	No	-
`camera_info`	Optional camera information to override the viewport state.	LOAD3DCAMERA	No	-
`width`	Width of the output preview in pixels (default: 1024).	INT	Yes	1 to 4096
`height`	Height of the output preview in pixels (default: 1024).	INT	Yes	1 to 4096

Note: When model_3d_info or camera_info are not connected, the node falls back to the 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`	Model information, either from the viewport state or the optional input.	LOAD3DMODELINFO
`camera_info`	Camera information, either from the viewport state or the optional input.	LOAD3DCAMERA
`width`	The width value passed through from the input.	INT
`height`	The height value passed through from the input.	INT
