I'm hoping this issue has been addressed elsewhere and I just can't find it, but can somebody tell me how (if it is possible) to fix the Iray rendering of eyes in Character Creator 3?  I dropped the CC eyes into my model and originally had the black reflections.  I followed the instructions on another post to manually correct it and that worked perfectly.  However, when I changed the iris color to purple, the Iray renders still showed the original unmodified eyes (blue) with default settings.  I know from tutorial videos the Std_Eye materials are PBR, and Std_Cornea materials are Digital_Human Eye which I have.  In the Iray render settings I am using Eye-PBR and Cornea as the preset substances.  Do I need to change those to get the proper eye settings to be displayed in Iray?  Here is a picture below to illustrate my problem.
