You can instruction to install it are here. This is a tool for keying all your biped limbs in one click including the root or COM. We decided that the vine anatomy needed more definition between the individual vines, so we went back into ZBrush and created Polypaint from polygroups. You might end up with a "few" modifiers, but then its up to you to collapse and leave the ones that you feel could be useful later to tweak your model. This awesome command panel is called Transform Toolbox.
