Since idusy is gone , i'll start updating this thread whenever a new Model Edit fix is out (this is Flying Piggy btw) .
If any of those links stop working for some reason , then you can always get the latest patch from the very same place that i got it http://modelchange.blogspot.com
Live Version (2.1.3) :
FileBeam download link
MegaUpload download link
Directions:
1. Put the exe inside your world of warcraft directory (example: C:\Program Files\World of Warcraft\)
2. Run the new .exe from your World of Warcraft directory inplace of WoW.exe to enable model changing (make sure you have your custom .MPQ setup)
3. The exe will open WoW.exe for you and you will be able to login.
4. After you've seen the swapped model, hit end and the program will close.
You may rename the .exe to anything you want
