Ok let me try to explain the motionLive set up.
Faceware is a program from another company [https://facewaretech.com/]. It does not belong to Reallusion. So the MotionLive software [https://mocap.reallusion.com/iclone-motion-live-mocap/buy.html] was written by Reallusion to fit Faceware and other third-party programs into the Reallusion, iClone world. Check https://mocap.reallusion.com/iclone-motion-live-mocap/default.html.
You also need profiles for the various motion Capture gadgets - whole body suits from xsens or perception Neuron, Leap Motion for hands and forearms. You are going to have to read up to find the cheapest passage through to motion capture.
I recommend iPhone and Live face [https://mocap.reallusion.com/iclone-motion-live-mocap/iphone-live-face.html] because you can buy an iPhone for about £30 per calendar month.
This kind of thing is called middleware - these are programs that allow two or more quite different programs to talk to each other.
