Hey everyone, heres a question from a total modding noob, I've just decided to jump into the modding scene and I've been following this tutorial to start out, I've reached step four and heres my probably really dumb question but when it says play through the first scene to create a clean save, does it mean go through the whole Escape Helgen speil until you exit to skyrim, or just get through to the autosave point before the character creation bit? Also any other quick tips about starting out would be much appreciated, thanks!
