Auto unwarp UV’s is based on an unfinished bonusTool called Automatic Wrap Map, which never really worked very well. Auto unwrap UV tool has more polish, works interactively as a tool, and will be available as a bonus tool when it is complete. For now the bt_autoUnwrapUVTool_beta2 script can be downloaded and used if you would like to give it a try before its release. Watch a demo on its use on the area.
