Game facial rigs are little tricky since most game engines doesn't support hybrid rigs like blendshape and bone based together. There is also a limitation in bone based joints like how much it can drive the animation data. Facial joint should be optimally rigged and paint weight distributed in order to get a muscle feel. But the challenge in game engines are the joint weights distribution to vertices. So we devised a rig that simulate this effect that can drive in game engines. It is tested in unity3d and plays smoothly. In addition blenshapes can be animated inside unity.
