I recently purchased Mastering Blender, the eBook, and have began Chapter 2. I am currently experiencing difficulty with the Smokestack activity. When I follow steps 1 through 4, I do not get the same Unwrap result as shown in Figure 2-8.
This is a link to the Blender file of my result: http://www.pasteall.org/blend/38699.
As you will notice, there are seven parts (versus Figure 2-8's six) and also the smallest part is a closed circle (versus Figure 2-8's semi-circle). I had gotten the result shown in the book on one attempt, however, I had missed a step and had to reattempt the activity and could not achieve the same result. How to match Figure 2-8?
