Preview3DAdvanced - ComfyUI Built-in Node Documentation

This node displays a 3D model preview in the UI without saving the file to the ComfyUI output directory.

This node displays a 3D model preview in the UI without saving the file to the ComfyUI output directory. It saves the model to a temporary file and passes through the model data, model information, camera information, and preview dimensions for further processing downstream.

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, or any supported 3D format
model_3d_info	Optional model information metadata. Advanced option.	LOAD3DMODELINFO	No	-
viewport_state	The current viewport state containing camera and model information.	LOAD3D	Yes	-
camera_info	Optional camera configuration for the 3D view. Advanced option.	LOAD3DCAMERA	No	-
width	The width of the preview in pixels. Default: 1024.	INT	Yes	1 to 4096
height	The height of the preview in pixels. Default: 1024.	INT	Yes	1 to 4096

Note: When camera_info or model_3d_info are not connected, their values are taken from viewport_state when available. If viewport_state contains no camera information, camera_info is None. If viewport_state has no model information, model_3d_info defaults to an empty list. If viewport_state is not a dictionary, it is treated as empty.

Outputs

Output Name	Description	Data Type
model_3d	The 3D model file passed through from the input.	FILE3D
model_3d_info	Model information metadata, either from the input or from the viewport state.	LOAD3DMODELINFO
camera_info	Camera configuration, either from the input or from the viewport state.	LOAD3DCAMERA
width	The width of the preview in pixels.	INT
height	The height of the preview in pixels.	INT
