UV MAPPING:
Preparing UV shader - Standard execution time: 2 minute (step 37 to 49).

37
Select the body of the pencil and open the UV mapping window.

b LMB:select RMB>LMB:UV Mapping

NB: all texturing can be made with Wings3D Materials and rendering in Yafray (or another...).
Here the purpose is to export the UV map to a renderer so we just need the topology of the pencil but many other method are possible...

38
Select all faces and choose an Auv chart color. Deselect all.

CtrlA RMB>LMB:AuvChart space

39
Continue selecting and coloring parts of the pencil, choose a different color for each; here 'top wood' and 'top lead'

LMB:select parts RMB>LMB:AuvChart

40
Vertex, Edges and Face selection are the same as modeling window.
NB: for the 'bottom wood' part don't forget the little inset (=72 faces)...

LMB:select parts ... etc.

41
Deselect all.
Select the edge loop along X axis

space e LMB:select 1 edge l

42
In Y view, deselect half of the selected loop.

y Ctrl+LMB:deselect

43
Return in camera view and mark this edge for cut.

r RMB>LMB:Mark Edge for Cut

Other ways: with hard edges (like step 17 and this 'half edge loop') made in modeling window OR with Material for each parts (and this 'half edge loop') made in modeling window, we jump directly at step 44! ;-)

44
Ready to Unfold the pencil! Open the edge menu and choose 'Continue', then 'Unfolding'

RMB>LMB:Continue LMB:Unfolding

45
All parts are unfolded in face groups. Create the texture...

RMB>LMB:Create Texture

You can scale, move, rotate face groups
for a better handling of the texture.

46
Choose some draw options (here only edges are needed) and close the UV window.

LMB:select options ret LMB:close UV window

47
You can see the 'edge' texture applied on the pencil. Open the 'Outliner' window and select the 'Diffuse' map.

Window menu:Outliner LMB:select 'diffuse'

48
Export this Diffuse map to a suitable format for you (jpg, tif, bmp, etc)

RMB:Export...

49
Export the pencil to your renderer (here 'VRML2 + UV' a free plug-in by D.A. COY)
Yes, I make no 'smooth'... what for? |:¬)
Save the Wings file. That's all.

File menu:Export... File menu:Save

50
Open the diffuse map in your best Paint program (with layers) and use it to make shaders for your renderer.

In this  illustration  I simply make 1 bump map,
1 mask for gold text and 3 diffuse maps
(one per pencil). Shaves are made with 'Extract region' of top 'wood' part.

The 'home' and 'exemple' pictures use this method with Wings3D 0.98.20c (modeling), Gimp 1.2.5 (painting), StrataStudioPro 3.9.1 (rendering) and MacOSX 3.3
on Apple G5.

You can return to the normal life... Bye.
