Quote - This rigging tool is called ?
In what App ?

It is a bunch of tools (Anzovin Rig tools for Maya).

It can be done in more than a few applications now, just in various ways. Basically every bone is a divisible spline, and there are some interesting joint options that drastically speed up the rigging process, which drastically cuts down on the weight mapping required to get a joint to work.

Check these video's out if you didn't follow the link in the last one..

This is a fairly new approach, and the results speak for themselves.

No idea when it will show up in an app near you, but it needs to.
