Hi,
the way Robert uses alpha channels is one
way to do it, but with POV 3.5 you can also use
pigment_pattern and this has some advantages:
1. You do not need to compose the texture map
together with the transparency map, so it's easier
to handle.
2. You can still use specular highlights, and that is
impossible with the "alpha channel technique" 'cause
the highlights are also applied to the invisible parts.
Basicly this is the same technique I have used for
the grille in my Marshall top+speaker image.
Soon I will post a short tutorial to
povray.binaries.tutorials to make this more clear.
And anyway it's a good idea to visit DigitalBabes
for the translash.jpg image.
What poser figure do you use, I thought it is the
p4woman , but you do use Poser 3 ???
so long

..ahem, well you are right.
I have never tried to render a face close up with POV.
It is indeed not so easy to create realistic looking eyes
but I still think it is possible. See my face post in this ng.

P.S. sorry for the mail, I've pressed thewrong button.

Sorry. The P3 female has completely different geometry to the P4 female,
so the existing Poser transmaps won't fit. You will have to build your
own after all.
Once you've mastered transparency maps in POV, it might be worth taking
a look at the DigitalBabes hair. It doesn't look quite so good in Poser3
because that doesn't support transparency maps, and you'll have to
convert the texture from JPG to TIF, but it will look so much better in
POV (see the full-size rendering of the model in my tutorial for an
example).

Yes, thats right, the Poser 3 Nude Woman does not work with the poser
4 eyelash transparency map. But it shouldn't be so difficult to create one
and 'cause I think this would be useful for all Poser users I will create
one and post it to this ng when it's done.
But the other things I have done with the texture should also work with
the poser 3 figure so here are some ideas:

>Scarlet}}
>#declare OBJuvPOV_Texture_OBJuvPOVtoeNails = texture {OBJuvPOV_Texture}
well, thats fine, so you did use a converter with the uv-information intact.
I would change the textures declarations like:
#declare P_Body = pigment { image_map { png "../../poser/OBJuvPOV.png"
interpolate 2}}
#declare F_Body = finish { ambient 0 diffuse 0.6 specular 0.04 roughness
0.06 metallic}
and then do some variation like:
#declare OBJuvPOV_Texture_OBJuvPOVskin = texture {
pigment {P_Body}
finish {F_Body}
normal {granite 0.12 scale 0.02 }
}
I think for the P3 woman you have to scale the normals much smaller to
look good.
...
#declare OBJuvPOV_Texture_OBJuvPOVlips = texture {
pigment {P_Body}
finish {diffuse 0.60 specular 0.33 roughness 0.015 metallic 0.5} // a
little glossy
normal {granite 0.1 scale <0.045, 0.15, 0.045> }
}
texture {
pigment {rgbt <0.1, 0.0, 0.4, 0.75> } // apply the color for the lipstick
}
..and so on, maybe a small reflection for the fingernails and higher
specular values for the inner mouth.
I have also added variable reflection to the eyes, but as you can
see, they still do not look real.
... and finally the eyelashes:
#declare LashTrans = texture{ // the invisible part
pigment {rgbft <0.008 , 0.005, 0.033, 0.0, 1.0> }
finish {diffuse 0.56 specular 0.0}
}
#declare LashText = texture{ // the lashes
pigment {rgbft <0.008 , 0.005, 0.033, 0.0, 1.0> }
finish {diffuse 0.56 specular 0.5 roughness 0.019 brilliance 1.5}
}
#declare LashPat = pigment { // the trans map half sized to save memory
image_map {png "/People/Brows&Lashes-2" interpolate 2}
scale <0.5,1,1> translate <0.5,0,0> // this scaling is only for
// the map I did
use to save some
// memory!!!
}
#declare OBJuvPOV_Texture_OBJuvPOVlashes = texture {
pigment_pattern{LashPat}
texture_map {
[0.05 LashTrans ] // you can adjust these values to
[0.85 LashText ] // make the lashes look more or less thin
}
}
I have used the same technique also for the eye brows, so there
is only one map file for both, the brows and the lashes.
But this is not so important for the moment.
What you need now is a small transparency map that fits the p3woman.
You can search the web for something like this, try to do one by yourself
or wait 'till I have drawn one. (Maybe tomorrow.)
so long

It might be of interest to note that I hear tell they're
gonna be releasing Poser 5 later this year...I do hope
it requires less hacking just to make something look
decent than Poser 4...also it pisses me off these
websites that sell Poser models for $50 or more, just
for something that should be part of Poser already...:P
