Volumetrics and transparency

toms7098

I am getting transparency problems when I use the "classic blowout hair" in the volumetric atmosphere prop from "render studio 2.0". Please see the attached pictures showing my scene with both the hair and atmosphere, without the atmosphere, and without the hair. This issue has been present in quite a number of Daz Studio versions. At the moment I am using the latest stable 4.20.0.17 and public beta 4.20.1.38.

 

Searching the forum for previous answers, I have tried adjusting the cutout opacity on the hair surfaces from 1.0 to 0.99, without any visible improvement. I have also tried adjusting the max path length in the render optimization settings from –1 to 64, 128, and 256, likewise without any visible improvement.

 

What do you suggest I do?
