Wow. This is a very complicated video! A little unnecessarily complicated I think, I would recommend watching the last few minutes from 11:30 to the end with more attention, it is much easier to understand there. The rest of the video is confusing and over complicated for me and sounds actually scary… there is no need for that. It’s just 3D, if you mess up just make a new file and try again and learn from your errors. Nobody gets hurt, and the world won’t end… i think 
Lets go make nice 3D now 
and above all, just have fun doing it.
