Scripts in the buttons category can be used in both Anime Studio Debut and Anime Studio Pro by placing them in the \scripts\tools directory of the Anime Studio installation directory and adding the name of the "button" to the _tools_list.txt file located in the same folder. These scripts can also be used with Anime Studio Pro only by placing them in the \scripts\menu directory of the Anime Studio installation directory. Once placed there and Anime Studio is relaunched the menu scripts will be available for use.
Use this script to copy and flip or "mirror" bones of a skeleton or rig from one side to the other adding an extension to the name. It will also mirror constraint targets if the target bone is also flipped and renamed.
