You may remember that in early 2014 I experimented with growing hair 
using POV-Ray code (see image attached). I remember now that I did this 
out of frustration with an apparent problem to convert Poser-generated 
lines to tubes in Poseray's latest build. I need to investigate further 
if this is: (1) a Poser problem (I currently am using Poser Pro 2014); 
(2) an export problem from Poser to an .obj file; (3) a particular 
Poseray problem. In the past, I did successfully convert Poser-generated 
lines into tubes, so it must be a later issue.

Does anybody here possibly has met with identical problems? please let 
me know.

Testing different Poseray versions with a beard/line test model from 
2011 I know did work correctly, it appears that the /latest/ Poseray 
version correctly converting lines to tubes is version 3_12_2, and 
possibly 3_13_15_beta (there was a file loading problem but creating a 
tubes conversion seems to work). Neither version 3_13_19 nor 3_13_23 do 
any conversion. Those are the versions in my possession.

Further careful testing shows me definitely that Poseray does not 
convert correctly from lines to tubes.

I shall contact FlyerX.

Thanks to the bug report from Thomas, the issue should be fixed now. You can
download the new version from PoseRay's site:

https://sites.google.com/site/poseray/

It has some other small updates too.

regards,

FlyerX

I'm curious what you expected it to look like.  It looks very dollish, 
but what was the desired effect?

I general I recommend against using dynamic hair with POV-Ray. It rarely looks
good. Trans-mapped hair looks fine but dynamic strand hair needs many more hairs
which need to be converted to tubes increasing the poly count massively. POV-Ray
also needs a better handling of the specular for strands to look better.

I think there is latitude for experimentation here. The one example 
where dynamic hair from Poser works rather well is with beards, if they 
are short. Otherwise, I agree with FlyerX that it is better to use 
trans-mapped hair for the time being.
