Can you explain what a unified rig is and why did you choose to use it for Star Citizen?

Before he explains what it is he'll explain some pre-cursor. There's a first person and a third person, and you only need a simple rig as most games are single player, but as games became more complex, people look down and want to see their legs and so they need to add another rig. Finally most games are multiplayer nowadays which means a third rig, so you'd have three rigs plus animation for first and third person systems. Unified rigs only have one skeleton, but it can take a little bit longer to get animations setup correctly, but it's much easier in the long run.
