I agree. The idea to use tubes might indeed be a much better solution than 
the ribbons. Looking forward to that!
Yes, less hair and larger texture areas are what I am favoring too. The 
problem then is how to texture that correctly. I think uv mapping would be 
necessary in Poseray, but I have not yet found out what type of mapping 
would work best. Using the ribbons, I shall experiment further along that 
line.

Thank you Janet for your comments! Yes, the kinks are translated to Poseray 
as far as I am aware of that. If you compare carefully the Poser "original" 
and the different conversions, you will see that the kinks correspond to the 
shadowed areas.

The hair/beard consist - in the Poseray conversion - of a root mesh (against 
the scalp) and a hair mesh. My impression is that they do not meet correctly 
thus giving the impression of the hair floating some distance from the 
scalp. By the way, only using the root mesh gives the impression of a badly 
shaven figure :-)  That could be a line to explore!

Yes, two hair props. I mentioned that also in my original message, towards 
the end, in a more cryptic way I admit as I did not want to go to deep into 
prop building and so forth. However, that would be the best solution. I 
shall certainly explore that avenue too.

I have to experiment further with the dynamic settings of the hair, 
especially the falling down. I used a pretty extreme setting  here.

Janet, would you think that the resolution of the skullcap/beardcap (i.e. 
finer or coarser mesh) influences the number of guide hairs and hence the 
total number of hairs in Poser? I am not sure and I have not tried this out 
yet, but that seems to be the case.


Oh, one thing in general: using radiosity with these hair/beard meshes is 
terrible. Render time rockets upwards tremendously. Something to keep in 
mind.

Thanks!! Excellent idea!

Here is an update.

Following the suggestions of Yadgar and Janet, I changed the dynamic 
settings in Poser. I made hair longer and it falls more naturally now, 
especially as I checked on the collision detection. I used a coarser mesh 
for the beardcap and, indeed as I suspected, the beard is sparser (with the 
same hair settings). I made it stiffer than the hair too. For both, I used a 
simple gradient y texture, uv mapped cylindrically along y in Poseray.

Comment 1: there is an issue with the root to hair transition. I probably 
have to play with the pull down and the root stiffness settings...

Comment 2: I deliberately used a fairly wide ribbon setting. I would like to 
see if I can get an image_map uv mapped on them...

Sorry. Should have included the image of course.....

And this is a version with an image_map and corresponding transparency map.

I edited a couple of hair maps from Kozaburo (in Poser 6) and applied them 
to the figure in Poseray. Cylindrical uv_mapping around y.

I believe this looks already pretty convincing, xcept for the beard, but 
that needs a higher number of hairs to obtain the same effect.

It makes me want to go and play with ribbons now. :) I bet you could get it
even better by transitioning the ends to transparent. Do all the ribbons
use the same UV mapping?

The UV mapping is the same for all. U is along the ribbon and V is across.

I did use also a transparent map, specially for the ends, but I think I have 
to scale down the uv mapping a bit as it does not seem to appear in the 
image.

Maybe something like this? I was trying it out. Renders slow, needs higher
max_trace_level, wouldn't even wanna try radiosity with it. lol
