Actually, due to the way scripts work, as long as anything shares the same name as the components you listed within THAT script, itll be affected by it.

For example, i rigged this Sonic mesh with the rig generator that comes with XSI, that will always maintain the same naming conventions no matter what. So technically this particular script can work with ANY rig that was made with it.

However, i CAN definitely make another one detailing how to do a trick or two, such as keying, or accomplishing redundant tasks with the click of a button, for sure!
