To reiterate what I said, I bought a material collection of almost 100 material two years ago for Cycles. I can use all of them in Blender. Hardly use any of them in Poser for several reasons:

1. Poser doesn't read Blender cycle node files.

2. Poser is missing several of the key nodes needed to make those materials.

3. I can and have tried to rebuild several nodes in Poser's material room, but it's hard. As I said, Poser is missing some of the nodes needed. And the material room nodes jump around like Mexican jumping beams on a hot skillet. It's confusing.
