Cinema 4D...

So I have this working rig from last year-

-which I could switch out with my new artwork so I won't need to redo the rig. Once I reloaded the parts...

I moved the joints and the artwork so that they slotted back together. 

Now the character is generally poseable, but the limbs are a little messy, and somehow I think I've damaged with the rig. I'll have to find a solution tomorrow.
