Just reading this thread and felt to cold shower of being left way behind. In the past, I would simply script shaders in Python. Worked for Poser AND Blender. Still have Poser 11 and was thinking of scripting a quick-n-dirty skin shader and - horror of horrors - come to realise that Superfly and Firefly are two different critters. And whilst Blender has 80 Cycles nodes, Poser only has some 60-odd of them. 

Otherwise I'd give you a quick solution you could run in Python, Red. Unfortunately, in my absence, they've moved the cheese. 🤨
