This button or menu script can be used to copy and flip bones from one side of a "root" bone. For example to flip the arm and leg bones of a character skeleton. The script can also copy and paste without flipping. The script is quite simple actually and works based on an "extension" of the bone name and must be a child of at least one bone NOT being flipped.
Installation
Method 1 - Button installation
Unzip and place both files into the scripts\tools\ directory of you Anime Studio installation directory. Open the _tool_list.txt file in a text editor. Add the following line of text as the last item under the "Group bones" section:
button hv_copyflipbones ...
Be sure to include the "..." at the end. If you wish to use a keyboard shortcut replace the "..." with the letter of you choice. Make sure it is not already in use by another tool in the _tool_list.txt file.
Method 2 - Scripts Menu item (Anime Studio Pro only!)
Unzip and place the hv_copyflipbones.lua file ONLY into the scripts\menu\ directory of you Anime Studio installation directory. If you like you can create a new folder in the menu folder to place this script into.
Usage Instructions
Example:
hand_left
forearm_left
bicep_left
chest

The hand and arm bones would flip based on the "chest" bone which is the parent or "top" of the chain. The chest bone does not have the "_left" extension and would not flip. If the chest bone or top bone of the chain has the same extension as the bones to be flipped the script will fail. If any of the bones have the SAME name the script will fail.
