The difference in the two files is the "Mobius Standard". Back in the heyday of Poser3, the mighty Mobius, (bows in the direction of greatness, LOL), posted a figure that was coverted to a higher number of polygons, giving it a smoother, more realistic look in closups and portraits. It is a memory cruncher though, and crashed many an old pentium that tried to use it too much. (Mine included =P ) I had not seen a P4 conversion of the Mobius HiRes on the Forum, so I thought some old time Posers might find it useful. But Veth is there in her standard P4 configuration too, so folks have a choice. Hope that clears the confusion up. =)
