My first EIP for curly - or better ribboned - hair. See the Discussion in
p.t.poser for more information.

Michael

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!

Thomas

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.
