Website/Download.html for Mac OS X installations. After you have installed the software, open the
smokestack.blend file and follow these steps:
To create a flat UV mapping, you need to define places on the 3D mesh where the geometry will be “cut.”
This is done by adding seams. In this case, it will be quickest just to use the default Loop selection to select the
