Please take the time to read all of the post if you are going to attempt to use this as if you read later on in the posts there are some that need to be take out as they some make models purple and also cause some not to work.
Also Using this causes you to load all of these models from the start not just when you enter a zone so it could affect some peoples loading times considerably.
Again please make sure you read all of the posts included in that link.
