no way, because Vivaty Studio 1.0 Beta cant import no one *.kmz from 3D warehouse.. for example this:
http://sketchup.google.com/3dwarehouse/details?mid=9a1873290b3bb4cfc352abdaf0bfc048&prevstart=0
so how I can import this model from link to sketchup.. and why some models has both file KMZ and SKP and others only KMZ if we cant use it
