I recant the EZSkin comment.  ATM, the Miki 4 P13 skin shaders are useless in the preview room.  Whoever did the conversion was not aware that the PhysicalSurface is not stable on its own to show a decent preview.  If the techs are keen on dropping the PoserSurface sometime in the near future, they need to fix the PhysicalSurface first.
