SavePointCloud - ComfyUI Built-in Node Documentation

The Save Point Cloud node saves a 3D point cloud file to the output directory and optionally provides preview data for the 3D viewer. It handles file naming and saving, while also passing through camera and model information for display purposes.

Inputs

Parameter	Description	Data Type	Required	Range
`model_3d`	Point cloud file (.ply)	FILE3D_POINT_CLOUD_ANY or FILE3D_PLY	Yes	-
`filename_prefix`	Prefix for the saved file name (default: “3d/ComfyUI”)	STRING	Yes	-
`viewport_state`	Current viewport state containing camera and model information	LOAD3D	Yes	-
`model_3d_info`	Additional model information for the 3D viewer	LOAD3D_MODEL_INFO	No	-
`camera_info`	Camera information for the 3D viewer	LOAD3D_CAMERA	No	-
`width`	Width of the preview display in pixels (default: 1024)	INT	Yes	1 to 4096
`height`	Height of the preview display in pixels (default: 1024)	INT	Yes	1 to 4096

The saved file is written to the output directory using the filename_prefix with a 5-digit counter appended (for example, 3d/ComfyUI_00001.ply). When the optional camera_info input is not connected, the camera information is taken from viewport_state; similarly, when model_3d_info is not connected, the model information is taken from viewport_state (or an empty list if none is available).

Outputs

Output Name	Description	Data Type
`model_3d`	The saved point cloud file	FILE3D_POINT_CLOUD_ANY
`model_3d_info`	Model information for the 3D viewer	LOAD3D_MODEL_INFO
`camera_info`	Camera information for the 3D viewer	LOAD3D_CAMERA
`width`	Width of the preview display	INT
`height`	Height of the preview display	INT
