This is FYI only
The latest version of Google Sketchup 7.1 is not compatible with latest papervision3d. A kmz created using sketchup 7.1 does not render properly in Flex when you use kmz parser to load the kmz file.
Currently, the solution is to downgrade to 7.0
So far, I haven't found out if 7.1 is being fixed or if the papervision folks are fixing it on their end. But, it is a major issue that cost me many hours trying to figure out why.
Hope this helps anyone trying to load 3D models into Flex for Google 3D Maps overlays.
