Quote - A few points Cage:-

In the Poser surface node of your shader the Diffuse Value and Specular Value should be 0, the hair shader uses the alternate diffuse.
In the Hair node set the root softness to 0 and check the Opaque in Shadow box.
I don't know how many growth groups you have on this hair but if it is only one then the total number of hairs is low. You really need about 20,000 hairs in total.
The skullcap is visible in the render,change it's material to transparent.

 

Thank you.  There is no skullcap, in this case.  That's a scalp material on the actual figure head, which was set to a darker material to try to keep him from looking like he's balding.  (As noted, the character has only worked decently in distant shots.  :unsure:)

Yeah, Diffuse is still set to 1, isn't it?  Huh. 

I guess the root softness is explained above.  Last I read, one was advised to un-check "Opaque in shadows", because that feature caused Really Slow Renders.  Is it faster, now?  If it's still slow, I'll leave it un-checked as a whaddayacall optimization.

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
