Instructions
Download Wrye Bash to your PC. The best way is to download and run Wrye Python. Then download the .zip or .exe file, depending on your preferences. If you're unzipping, you need to set up a directory for "Oblivion" installation first.
Start your game and choose a name, gender and race for your character. Then, save and quit the game.
Open the Wrye Bash program by double-clicking on the icon. Go to "Saves" and choose the game file that you just saved.
Right-click on the screen and choose "Import Face" to get a dialogue box. Here, you choose the game file again. Click "OK" to import the face.
