Ashley & Fantasy Hair - they don't render properly

Hi there, i have encountered a problem with two hair styles - namely Bluebird3ds Ashley Hair and 3D Universes Fantasy Hair. I got both in sales recently and now wanted to try them out, but they do not render properly with iRay and the "Dome and Scene" mode. The first iray iteration seems ok but then they become more and more white-ish and shapeless. Using "Sun-Sky only" they seem fine. The first picture shows Ashley Hair on V7 with SunSky and DaS, and the other one Fantasy Hair on Brenna with black (!) iRay materials applied.

Other hair styles do not cause this problem for me. I tried resetting the render options, re-installing both the Hair products and DAZ3D itself, to no avail.

Does anyone have an idea to what is the cause of this?

Thanks!

    If I remember correctly, the culprit is backscattering. It doesn't play well with certain render settings, for some reason. Try going into the Surfaces tab and turning it off.

    Hey, that worked! Turns out the setting "backscattering weight" defaults to something like 0.15 when applying a material, and turning it off eliminates the problem. Thank you so much!
