Quadruped Rigger offers an easy rigging solution for horses and similar animals to provide a basic character rig for animation.
The script also fills a gap in available auto-riggers as there are not many that provide an easy way to quickly create a quadruped rig, especially suitable for beginners.
The resulting rig features only basic functionality in order to keep it simple. There are no toes, facial or any other high level controls.
Quadruped Rigger creates a basic and stable rig which can be build upon.
At the current level of the script the rig does not properly allow to create characters like cats and dogs, because of the difference in joint structure and articulation.
Though, this may be added in future versions.
