PreviewGaussianSplat - ComfyUI Built-in Node Documentation

The PreviewGaussianSplat node displays a 3D gaussian splat file in a preview window without saving it to the ComfyUI output directory.

The PreviewGaussianSplat node displays a 3D gaussian splat file in a preview window without saving it to the ComfyUI output directory. It accepts a 3D model file in various gaussian splat formats, saves a temporary copy for previewing, and passes the model data through for further processing in the workflow.

Inputs

Parameter	Description	Data Type	Required	Range
model_3d	A gaussian splat 3D file.	FILE3D	Yes	splat ply spz ksplat
model_3d_info	Optional metadata information about the 3D model. When not connected, the node uses the model info from viewport_state.	LOAD3DMODELINFO	No	-
viewport_state	The current state of the 3D viewport, including camera and model information.	LOAD3D	Yes	-
camera_info	Optional camera information for the preview. When not connected, the node uses the camera info from viewport_state.	LOAD3DCAMERA	No	-
width	The width of the preview render in pixels (default: 1024).	INT	Yes	1 to 4096
height	The height of the preview render in pixels (default: 1024).	INT	Yes	1 to 4096

Note: When camera_info or model_3d_info are not provided, the node falls back to the camera and model information stored in viewport_state.

Outputs

Output Name	Description	Data Type
model_3d	The input 3D gaussian splat file, passed through unchanged.	FILE3D
model_3d_info	Metadata information about the 3D model, either from the input or derived from the viewport state.	LOAD3DMODELINFO
camera_info	Camera information for the preview, either from the input or derived from the viewport state.	LOAD3DCAMERA
width	The width of the preview render.	INT
height	The height of the preview render.	INT
