So for the last 3 months I've been looking for a better flow to make, rig, animate and set up my characters for the engine that isn't a 3 week + process for all the features i need in a character then i found IClone so friday I've been looking at videos for hours and now I think im going to try to get 1 character remade and fully in engine by end of day Saturday. 
I'm also trying to record the whole process in this playlist.
