Click on 'Add-> Mesh-> UVSphere'. Set segments to 4 and rings to 4. Click OK.
In your view the newly added mesh will not be visible. This is because it is covered up by the cube. However the mesh should be already selected and a set of arrows should be visible.
Left-Click on the green arrow and hold the mouse button down and move your mouse till your mesh is exactly above your cube.
Click on 'Add-> Mesh-> Cylinder'.
Set vertices to 6.

Step 2: Creating normal maps.

Switch to the Normalmap window and checkmark Wrap.
Set the Height source to Alpha. Now set the Scale to 6. And the filter to one of the following:

  1. 4 Sample – Very grainy. Use for rock or other rough textures.
  2. 3x3 – Grainy. Use for scratched metals or other rough textures.
  3. 5x5 – Smooth. Use for smooth metals and wood.
  4. 7x7 – Smoother. Use for cloth and furniture.

When you have done that click the Ok Button. File-> Save As. Set the name to I_n.tga and uncheck RLE Compression and make sure the origin is Top left. Click the Save button.
