This is just Lawlder's mod, "Follower Amata" ported to work with TTW. All credit goes to him for the original work.
Mostly, this is just a basic conversion, and then modification of a few scripts to disable FNV's automatic companion wheel. Lawlder went through all of the hard work, making Amata fully voiced as a companion, etc.
For instructions on how to get Amata as a follower, go to the Nexus page. I have tested this conversion through the character generation and it works fine.
THIS MOD SHOULD BE VIEWED AS A "DEMO" - THERE ARE STILL SOME ISSUES - particularly, Amata doesn't seem to like to be fired. If anyone else wants to continue work on porting this mod, please feel free.
