Oh I wonder if that was what stuffed it up, I imported all the parts for all the eyes then started saving them outHmm........ Ahh nod ok was just curious as sometimes when you save out an object from Poser and like have the dome on or the ground it xfers into the obj scene and Daz only wants one object in the scene when imported.
Thanks that will be handy if and when I do Iray mats not much good for 3Delight thoughIn Iray with Ubershader it will be very easy. That's the situation metalness/roughness workflow was made for.
1. make bones mat
2. draw bw mix map and put it in metallness slot (0 for bones, 1 for metal, in between if you want rust)
3. edit all other maps accordingly, say if you use tranclucency or SSS set it to zero in metal areas.
And look here for better version of this instruction - PBR Guide - very short and very to the point.
