Bipedal Rigging
​
Below is some function I made in this Maya rigging demo:
​
Function 1: Arm IKFK
The arm rig consists of three joint chains: FK, rotate-plane IK, and a driver joint chain.
Users can switch between FK mode and IK mode via the Arm FKIK attribute on the clavicle control.
-
When Arm FKIK = 0, the arm is controlled by FK, using shoulder control, elbow control, and wrist control.
-
When Arm FKIK = 1, the arm switches to IK mode, controlled by the IK handle.
​
Function 2: Spine IKFK
The spine rig supports both FK and IK.
Users can switch between FK and IK using the Spine FKIK attribute on the torso control.
-
When Spine FKIK = 0, the spine is controlled in FK mode from spine 0 to spine 4.
-
When Spine FKIK = 1, the spine is controlled in IK mode via the chest control and pelvis control.
​
Function 3: IK Leg and Reverse Foot
Each leg has a dedicated foot control, a pole vector knee control, and two additional controls for the ball and toe joints.
The rig includes two joint chains for each leg:
-
Primary leg chain (hip to toe).
-
Reverse foot chain, properly oriented for stable foot roll and movement.
This setup ensures precise IK leg motion and foot articulation.
​
Function 4: BlendShape
Facial expressions can be controlled using BlendShapes.
Users can adjust BlendShapes in the face control's attribute editor, setting values from 0 to 1. This allows animators to easily keyframe facial deformations.
