You apparently still have the demo, so how are you supposed to build anything decent?
Your screenshot thread was a failure, and this will be a failure as well. Wait till you buy the game before opening stuff like this, and at least make sure you're experienced enough, include proof that you are good with this stuff, and know what the forget you're doing before opening stuff like this as well.
To let you know, you do not need to do it! It is optional!
We're not 7 year olds like you, we don't need to be told that we don't need to do what some insignificant moron tells us to do.
