" For you looking for a Maya version, I wrote this simple exploder script to learn python some months back.

https://dl.dropboxusercontent.com/u/700791/Scripts/masterExploder.py

The way it works is that it will match the object name, and sort between types using the suffix. This means that your lowpoly/highpoly/cage/blocker need to have the EXACT same name, and using the suffixes _lowpoly, _highpoly, _cage, and _blocker. If your highpoly consists of more parts than your lowpoly you can put the highpoly meshes in a group that has a name matching the lowpoly.

When you run the script it will prompt you to input the amount of units you want to offset the meshes by. Also, it will key the meshes as gathered at frame 1 and exploded at frame 10. If you have existing keys or incoming connections it may cause problems. "
