Yep! Check this link here. Look for post that sounds like this:
"Export to Google Earth 4 (.kmz) MAKE SURE IT IS GOOGLE EARTH 4! Then, change the file extension from .kmz to .zip. In the folder that you decompressed, you will have a models folder and maybe a textures folder. If you color a model with only sketchup solid colors, you can turn them into shaders in unity, like the reflective buggy material. when you have the "models" folder, You can rename it and drag it directly into the assets box in unity. It will then load in there. open the folder in unity and drag the model file out onto the screen. Then you will have your model in unity."
i got no idea, as i have been asking supercheese to convert my sketchup files in to blender files, which i then ship of to Aubrey, as the models were the Sky Monster and the Sky King(which had the Sky Shark inside it) as those were really big objects, and not small one's in which to put in to a map, as they are there own map
