This looks really nice, and will probably brighten(dullify?) many desk scenes.
No, I won't make one(i can't get the papers correct at all)
*smile*
well, good work and good luck.
hm.. the text.. a text object translated and scaled rirght, and then with a
"golden" colour, and then difference it? I think that's how they look on my
pencils...

I thought that it was. What I was thinking was that instead of using just the
graphite pigment for the lead that you combine it with whatever wood texture
(and parameters ) that was used for the pencil in the texture for the cylinder.
I slapped together a real basic image, hope you don't mind. ;-]

cone { <-1, 0.001, -1>, 0.001, <2, 4, 2>, 1.2
texture {
planar
turbulence 0.4
texture_map {
[0.01 T_Wood23 finish { ambient 0.3 } scale 4 rotate z*-40 ]//whatever Wood
texture you choose
[0.2 pigment { rgb 0.65 } finish {specular 0.5 roughness 0.15 }]
}
translate y*0.6
}
}

The only thing I could add is that if you keep it as two
cylinders, add a certain randomness that places the lead
slightly off center, and possibly even the sharpened end.
When was the last time you were able to sharpen a pencil
in a perfectly aligned point?

That's what I call inspiration.
Cheers
Steve.
PS: thought I had one of my objects finished, now I've got to go
through the whole lot fixing the textures.

It'll be finished thes weekend I hope and will be posted on this
very NG for suggestions/coments, insults whatever.
Cheers

Been away for a bit. But getting back to this.....
Aha! I understand - and that would work great! Much less hassle than the CSG
chipping idea for the paint edge too - although I might toggle the two
schemes on a quality flag. Thanks!!
Aha!
