Fatima shares his rigging and walk cycle tool for Autodesk Maya called walkTool. The Maya script will allow you to create a complete skeleton with an FBIK setup and IK handles, and then provides an interface for creating a simple quick and dirty walk cycle procedurally, simply my choosing slider values for the various walk cycle components.
The walkTool procedurally constructs a complete skeleton for characters and it creates a walk cycle providing the users with an interface to adjust the different parameters of the walk
This is an interesting concept in character animation, where some tools will allow you to get to a starting point quickly… the old MAX footstep tool comes to mind. walkTool will allow you set step size, leg height, and hip rotation for both top and front. Check out the walkTool for Maya here.
