Step four: First Pass Render

By then end of your first session you should have completed at least stacking four rows or primative neo-cubes and boolean cut a door somewhere low on the side away from the wind.
You'll find that it is important to boolean cut the top of each row so that they begin to angle in towards the center of your circle. The angle should be increased with each succesive row.
Believe me..I wish I had figured that out earlier.

Obviously this process took sometime and so I decided to change the background lighting from day to night. This isn't necessary however. You can work it out however you'd like.
