  4. 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 theeditor icon in the header strip. 3. Enter edit mode and choose edge select mode, as shown in Figure bellow.

  5. UV MAPPING 4. Select the edges (Shift-RMB) that will be seams. Try to select areas that when cut willresult in the mesh being able to unfold into a flat pattern. Press Ctrl+E and choose MarkSeam from the pop-up menu. If you make the mistake of marking incorrect seams, youcan undo them with Ctrl+E ➤ Clear Seam, which is found just below Mark Seam in theEdges menu (see Figure).

  6. UV MAPPING 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 toflat-unwrap your mesh in the UV editor window. At this point, errors in seampositioning may become apparent (see some of the examples in Figure 5–6). Ifnecessary, fix the seams as needed and simply unwrap again.

  7. UV MAPPING • Once you are happy with the UV layout, save it. This can be done via UVs ➤ Export UVLayout, 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

  9. Add the texture to thematerial 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
