Getting ready to Model Swap:
Step 1) Download ttarch (http://aluigi.altervista.org/papers/ttarchext.zip
Step 2) Winrar and put it in a folder
Step 3) Find WDM_pc_WalkingDeadM101_data.ttarch2 in "C:\Program Files(x86)\Steam\SteamApps\common\The Walking Dead Michonne\archives\WDM_pc_WalkingDeadM101_data.ttarch2"
Step 4) Put it in the folder you put ttarch in
Step 5) Open application cmd.
Step 6) Type "cd C:\Desktop\(Wherever you put WDM_pc_WalkingDeadM101_data.ttarch2 for me ModelSwap)\ttarch(or whatever you named the ttarch file)
Without my words: "cd C:\Desktop\ModelSwap\ttarch
Step 7) Type this in the cmd window "ttarchext.exe 59 (this is the file being extracted)"C:\Desktop\ModelSwap\WDM_pc_WalkingDeadM101_data.ttarch2" (mattering on where it is for you then without quotes) C:\Desktop\ModelSwap\Data (this is where you want the extracted files to be it may be different for you)
Without my explanations "ttarchext.exe 59 "C:\Desktop\ModelSwap\WDM_pc_WalkingDeadM101_data.ttarch2" C:\Desktop\ModelSwap\Data"

Now to model swap:
Step 1) Find the models you want to swap. For example you want reuben to look like a sheep
Step 2) If you want Michonne to look like a Clementine you find the sk56_clementine200.prop and rename it sk55_michonne.prop
Step 3) Put it in "C:\Program Files(x86)\Steam\SteamApps\common\The Walking Dead Michonne\archives"
Step 4) Start Walking Dead Michonne. The props should be swapped
