Jockey Set from DO, Sickleyield, & Marieah in iray

Hey, I used the Jockey Set & converted with the Uber iRay converter but it seems the silks are two layers. A think outer layer and an inner layer. Trouble is rather than the traditional horse racing silks showing their pattern I am getting only color from the glossiness channel.
You can ignore the hair poke through on the DAZ Horse 2 and the Jockey as I know how to fix that. I am trying to set up a horse race render on a track.
How to fix to simulate real silks in iRay please?
Thanks.

Oh, it seems to be Refraction Index & Refraction Weight but I have no ideal of the correct value of these things in iRay for silks.
