KMZ, or Keyhole Markup Zipped, is a parsed Google Earth file.

KMZ material names, and child names, are located in a .dae file within the .kmz file. The .dae file can be found by renaming the .kmz file extension to a .zip file extension and then opening the .zip file and models folder.

Note: This tutorial is currently working through revision 910 ONLY.

Example
