Thanks again.
That shader tree will be a great help because time is my single biggest problem the 3D hobby and any time-saver is worth it's weight in gold.

As far as Poser 13 is concerned, you're preaching to the converted. Meaning if I could, I would.

Trouble is, I treated myself to a deal on Poser 12 this Christmas to finally give Physically Based rendering a go, now that I also have a suitable rig. Going to have to wait a while with a further Poser 13 investment.
