Fireflies in Real Hairy since upgrade to new DAZ Studio

I've rendered the same characters dozens of times. But since upgrading to the latest versions of daz Studio I'm getting fireflies with the real hairy chest hair. It is not an iray native product so I am recoloring it with the iray uber base and using a hair color to make it blonde. It worked fine before I upgraded. Oddly seems to be this product only, as REDZ bodyhair doesn't make fireflies. They are pretty big fireflies too. Long and odd looking. Any suggestions? I've tried different lights and it doesn't seem to matter.

    From the forum post about the update:

    4.9.4.113 (June 9, 2017)

    • Uber Iray Material
      • Added a "Dual Lobe Specular Reflectivity" property
      •  

    I wonder if the default value of that new Iray Uber parameter could be causing you a problem.

    Hmmm I may try just leaving it 3dl and see how it looks. I find the change frustrating though since I like the real hairy product for its closer fitting hair. Would be a Shame to not be able to use it with Iray shaders like before
