I am having a problem importing a sketchup model of a sports complex into google earth for a class project. Here is what it looks like in sketchup on the google terrain (all is well)

but now when I export to google earth I get bad rendering on the soccer fields - I have raised them a slight bit to avoid z-fighting if that matters

I was just wondering if I have a setting wrong to cause this or if I am just screwed on the quality presentation factor.
