We are now going to join the two UV islands' halves together, in order to improve the final look of the texturing; we are also going to modify, if possible, a little of the island proportions in order to obtain a more regular flow of the UV vertices, and fix the distortions we have seen in the last image of the previous recipe.
We are going to the use the pin tool, which is normally used in conjunction with the Live Unwrap tool.
First, we'll try to recalculate the unwrap of some of the islands by modifying the seams of the mesh.
Before we start though, let's see if we can improve some of the visibility of the UV islands in the UV/Image Editor:
Put the mouse cursor in the UV/Image Editor window and press the N key.
In the Properties sidepanel that appears by pressing the N key on the right-hand side of the window, go to the Display subpanel and click on the Black or White button (depending on your preference) under the UV item. Check also the Smooth item...
