That seems like it took quite some work, but it also looks rather neat that you can do all that.
thanks i'm trying to turn this into my career!! currently im just doing an internship for a game company so that's what this is all for.
i set up some great stuff today. what ive been posting is a parent animation rig for multiple characters. any animation made on the rig can be used on different equine-like characters. the rig lacks a tail, eyes or ears because these can all be added ontop of the shared animations using additive animation with minimal effort. its really exciting and all set up for Unity engine.
edit: this is also the exact same method i'm going to be using to mass-produce custom animal crossing characters for twitter on commission
