So why are you here well 3 reason
1. You're a watcher of my and this showed up on you watch list and you clicked it
2. I linked you to this as you the 1000th person to ask "Where did you get the model from"
3. you found it by chance while looking for sfm stuff on here

Whatever got you here welcome to how I make my model hacks, Everything you we need to know is in this guide include links to some extra stuff which you will find useful if you plan to do this,

Updated with a new link in the file

Anything i use in my SFM will come from
SFM workshop, http://sfmlab.com or was made by https://www.furaffinity.net/user/mutztuz/
and often i edit the VTF/VMT files to get the look i want in models.

feel free to ask questions
