StretchMaker is used to build stretchable limbs for character rigs in Maya. All stretching is created by building utility node networks instead of using expressions. This speeds things up on more complex characters.
The interface is simple to use and allows for as many joints as you like. And attribute is also, automatically added to a control curve.
PLEASE NOTE: This script has not been extensively tested. It works with great success under very standard situations but might not do so well under more complex situations. Please post any bugs you find.
