I was finally able to embed RenderMan shaders specifically designed for hair and fur.
It’s a wonderful add on that allows to use such shaders directly in DAZ Studio, and the quality of the output is way much better than the usual ambient occlusion shaders that often are used with hair.
I ran some quick renders (low quality settings, shading rate=0.75), only 20000 hair very thick (35x than average human hair), one distant light, with colors ranging from blonde to black and low specular intensity.
I’m now going to code the GUI interface so that it will be easier to play with those some more…
