It is a game fan video.I'm still not sure why I can not extract skeleton successfully from the game compression pkg. It really took a long time to rebuild whole skeleton and attach the mesh to bones. Design and Create the dancing action were also heavy work, for which I need to see a lot of tango videos.
I didn't do this one very meticulous. There were bugs both on action interaction and character model. However, more than expected, so many people love it... Anyway, have fun!
