Attached Link: Stewer's Firefly tips

To really explain the concept of procedural and/or nodal shaders (which includes P5 Materials) would take a rather thick book. There is a lot to cover because the process is so flexible and powerful. Much of this information is available on the internet, but unfortunately, very little has been published about the Poser-specific shader system. If you really want to learn how to use all this power follow these steps: 1) Read the Materials chapter of the P5 manual, Yes, its boring and not very detailed - but it is an overview of the process and you won't find much of this repeated in other tutorials. 2) Read ALL of stewers tips (see link above). 3) Download all the free materials you can (the ones at RDNA are good and you will find some here). Bring those materials into Poser's Material Room and study them. There are also some interesting materials included with P5 that you might want to explore. 4) Once you know the basics well enough to ask specific questions, you will find that there are several people here willing to respond, but most of us don't have the time to write a complete tutorial on this massive subject.
