Hi,
no, it only means that all kind of pano types like cubical, spherical, cylindrical and flat panos can be multires.
The 'slider-blending' itself is no real pano blending, there only distorted hotspots were used.
Normal panos can be only blended by using a loadpano() or loadscene() call to load the other pano. By using the KEEPVIEW the current view can be kept during blending, but an interactive blending like in the slider example is not possible this way.
Best regards,
Klaus
