I have been making several storm surge models along with several building models made in Sketchup to be run in Google Earth. The storm surge model is a SLOSH model designed for GE. The Sketchup models have been exported to a .kmz file and work great in GE, but when I flood them with the transparent storm surge layer the parts of my building models underwater do not show up while the extruded building footprints do show up underwater (the blue square buildings) . In past versions of GE it has worked great. Any idea how I can fix this?

Here's the one with no storm surge, working great.

And here's the one with the storm surge, not working.

Any help would be great. Thanks!
