Creating skins - mod tools required?

[Big Frank]

for creating skins (like darth vader and yoda) do you need to download any mod tools or anything?

 

or does the game come with an editor?

[Prime]

Just to be clear about what you are asking, skins refers to the textures that are used by the models. Models are the actual shapes of the characters. Are you watning to create new textures or new models?
