I've also written a good amount of documentation and created some visuals to help new and experienced avatar creators alike with creating Titanfall avatars.
I've also included three example avatars (As UnityPackages) to look over yourself and get a grip on things. They are:
Example Pilot Avatar
Example Titan Avatar
Example Quest Fallback Avatar
(All created in SDK2)
I'm excited to see what everyone is able to make with these, best of luck on your future projects pilot!
