Are there any "free" Open Source Motion Capture Software? That can also do any of the following.

1)Use your PC camera to move the 3D human made in Blender or Makehuman etc. eg. I move my hand, the 3D figure moves it's hand too.
2)Work in Blender or Makehuman, or "better," both.
The reason why I'm asking, is because I am making a "Fighting game," that is almost 12 years of hard work and planning. Talk about headache. He! He!
And motion capture is one of the "main parts of the process," for this game.
If not, then I'll have to get "$10,000 or more dollars" from my relatives to get one. Most likely I wouldn't get "So" soon.

I'd rather buy an Alienware or Asus Gaming Notebook with that money. Waaah!!.
