React Three Fiber Set Default Camera

To set the default camera in 2021+, use state.set exposed from useThree. Note that `setDefaultCamera` does not exist anymore, and every reference would use that.

“setDefaultCamera is not a function”

Instead, use the following:

const Camera = (props) => {
  const ref = useRef();
  const set = useThree((state) => state.set);
  useEffect(() => void set({ camera: ref.current }), []);
  useFrame(() => ref.current.updateMatrixWorld());
  return <perspectiveCamera ref={ref} {...props} />;
};
