I'm currently rigging a feline-humanoid character for a UE4 game project using the Rigify add-on. However, this character has some extra features than that of a standard humanoid, including a tail, whiskers, cat ears and hair that I would like to rig as well.
My goal is to animate the base Rigify humanoid to perform common actions (idle, run, etc.) that I can recycle for any humanoid character, but also somehow augment this rig to include this character's unique tail, whiskers, ears and hair to animate alongside the common shared animations. Does anybody know how one might achieve this?
