UV MAPPING

• To get an idea of the process, perform the
  following steps
• 1. Start with a simple mesh, such as a sphere or
  cube.
• 2. Split the screen into two views, and change
  one of them to UV/image editor, using the editor
  icon in the header strip.
• 3. Enter edit mode and choose edge select mode,
  as shown in Figure bellow.

• 4. Select the edges (Shift-RMB) that will be
  seams. Try to select areas that when cut will
  result in the mesh being able to unfold into a
  flat pattern. Press CtrlE and choose Mark Seam
  from the pop-up menu. If you make the mistake of
  marking incorrect seams, you can undo them with
  CtrlE ? Clear Seam, which is found just below
  Mark Seam in the Edges menu (see Figure).

• 5. When you think you have achieved well-placed
  seams, press A to select the full mesh, then
  press U, and then select Unwrap from the pop-up
  menu. Blender will attempt to flat-unwrap your
  mesh in the UV editor window. At this point,
  errors in seam positioning may become apparent
  (see some of the examples in Figure 56). If
  necessary, fix the seams as needed and simply
  unwrap again.

• Once you are happy with the UV layout, save it.
  This can be done via UVs ? Export UV Layout, at
  the bottom of the UV editor.
• Open the saved UV layout with a 2D paint program
  such as Photoshop or Gimp.
• Resave the image in PNG format

If you have a computer with a GLSL-capable
graphics card, you can set the 3D view
to Textured and the Display ? Shading attribute
on the Properties panel to GLSL to enable
the texture to show in 3D view
