My first EIP for curly - or better ribboned - hair. See the Discussion in

Those hairs looks good. Now, time to work on the beard: It looks totaly
fake, like glued on cork...

The hair is *just* a conforming hair map from Kosaburo, so no big deal
there.
The beard is really another matter :-( I am thinking that one may need
two superposed dynamic groups, one for the cheeks where hair is more
scarce, and one for the thicker parts. In any case, the texturing
remains a nightmare.

That is looking good indeed, although more like a fleece maybe than
human hair. Because of the density of the curls the hair looks very
heavy. Have you tried with a lower Hair Density? That may be one
solution. Another track to investigate is the use of transparency, i.e.
a transparency map. I am not sure, it depends on how the uv-mapping of
the tubes is done.
Good work, Michael!

OK. I investigated the uv_mapping and that appears to be nicely done,
with the seam along the length axis of each individual hair/tube.
Use of transparency maps is not necessary/recommended as the hairs are
too thin.
However, if needed/wanted, one can of course use transmit or better
filter, within the texture to play with the transparency of the hair.
The following material has been used for the attached image. Note the
gradient x for colour change from root to tip. No filter applied here
but it subtly alters the overall aspect when used. Advice: filter 0 at
the root; filter <1.0 at the tip. Be careful with the use of any warp as
this can upset your scheme.
The material used:
material {
texture {
uv_mapping
pigment {
gradient x
pigment_map {
[0.20 srgb < 0, 0, 0>/255 filter 0.0]
[1.00 srgb <255, 255, 255>/255 filter 0.0]
}
scale <1, 1, 1>
warp {turbulence <0.0, 0.01, 0.01>}
}
finish {
specular 0.2
roughness 0.005
diffuse 0.8
}
}
}
All comments welcome of course!

For the beard, the following texture is used.
This is more complex to get right. While I am satisfied with the
texture, the beard mesh need more work I guess.
material {
texture {
uv_mapping
pigment {
gradient x
pigment_map {
[0.00 srgb < 0, 0, 0>/255 transmit 0.8]
[0.10 srgb <171, 77, 14>/255 transmit 0.7]
[0.50 srgb < 0, 0, 0>/255 transmit 0.5]
[0.60 srgb <171, 77, 14>/255 transmit 0.0]
}
scale <1, 1, 1>
warp {turbulence <0.0, 0.3, 0.3>}
}
finish {
specular 0.2
roughness 0.005
diffuse 0.8
}
}
}

I'm not sure about the beard and the eyes, but the hairs are excellent imho.

The hair is a hair map, so no big deal :-)
About the eyes, if you mean the slight "squint" (strabismus), that seems
to be a problem with Poseray: It does not appear in Poser but only after
processing by Poseray. I shall have to ask FlyerX.
