Here you will learn about character rigging in Maya 2012 with some advanced features. The character basic skeleton is created with the help of joints set up. The model is in standing position with stretching arms. The model is now in wireframe mode. The character is rigging from joint set up. There are main joints at wrist, elbow, shoulder point and these joints are used for moving, rotating and stretching the arms for performing any action. It is better to use outliner; it allows you to modify the shape of the model along with joints. Here this tutorial is describing some information about wrist joints and from outliner setup; you can manage the setting for each joint separately.
From shoulder joints the character can be rotated for any kind of job. The chest joint is so elastic that it can be easily rotated for any kind of situation. The same is the case with leg joint set up where you can rotate the leg using rotate tool.
Make sure that other leg is also performing same job by rotating at X-axis. The joint set up is really amazing and it is not necessary that all joint set up should be same; the joints are created according to different character shape. Anyhow the following video is only showing you set up for model rigging in Maya 2012.
