v1.30 of The Rigging Toolbox is out.
Lots of code cleanup and UI improvements but the big new feature is IK/FK switching and blending for legs. This was by far the number one requested new feature with multiple users suggesting it “should be” easy to implement give the current switching and blending feature for the arms. Things are never as simple as they may seem. In this case it was a challenge to keep the foot-roll and associated IK foot control intact while switching back and forth between IK and FK. Works great.
