/**
 * Create a cube-mapped sky using six textures.
 *
 * @param assetManager from which to load materials
 * @param west         texture for the western face of the cube
 * @param east         texture for the eastern face of the cube
 * @param north        texture for the northern face of the cube
 * @param south        texture for the southern face of the cube
 * @param up           texture for the top face of the cube
 * @param down         texture for the bottom face of the cube
 * @param normalScale  The normal scale is multiplied by the 3D normal to get
 *                     a texture coordinate. Use Vector3f.UNIT_XYZ to not apply and
 *                     transformation to the normal.
 * @param sphereRadius the sky sphere's radius: for the sky to be visible,
 *                     its radius must fall between the near and far planes of the camera's
 *                     frustrum
 * @return a new spatial representing the sky, ready to be attached to the
 * scene graph
