The finished UVs of a character are not likely to be in one solid piece as was the case with the cube in the previous example. Instead, we will end up with lots of separate chunks of the model, called UV islands. Each of these islands is used to separate areas of high complexity into sections with minimal distortion. Since our character's head is the most complex area, let's start by marking a seam around the neck to separate it (don't worry, it won't hurt the dragon):
- Select an edge loop all the way around the dragon's neck (refer to the following screenshot).
- Press the Ctrl + E hotkey to bring up the Edge Context menu.
- Choose Mark Seam:
Hold Alt before clicking on an edge to select the whole edge loop; edge loops ...
