Hey guys, I wanted to share with you how to model edit in this patch.
First you need to download "SIG & MD5 protection remover" here: http://www.ownedcore.com/forums/world-of-warcraft/bots-programs/291383-patch-sig-md5-protection-remover.html
1. Start the program and select your Wow.exe
2. Check "Disable 'signaturefile' checkes" and "Maximize patch number limitation"
4. Apply changes
3. Extract your old MPQs and make a new folder called "base"
4. Put your old data into this folder
5. Create new MPQ (structure has to look like "base\Character\Human\Male")
6. Name it "wow-update-13624.MPQ" or higher number
7. Start wow
Enjoy model edits
