Yes, I'm experimenting too...

Here, for example, I also used the roughness map as a displacement map, with the result that more depth and structure can be seen in the surface. I'm sometimes very amazed at what fantastic results the Poser render engine is capable of. I don't pull my hair out, I usually tip over backwards in the office chair....:)

Sorry about the large pictures, but I'm sitting here in front of a 48" OLED monitor and it's difficult for me to take smaller pictures.
