This is my first autorig. It's inspirited by the chaintools by Felix Joleanes.
It would permet you to creat a chain tools with unequitable bones (that you created before hand) and a line ( the knot represent the emplacement of your controller ).
I would be happy to hear your feedback :)
The script on my site is the macroscript (a button for your interface). You have to click right on max top, select "customize", go to "tooldars", in category find "MaryryCoScript" and drag and drop the script in your toolbar. Then have fun with it :)
