Silke,

You said "So if anyone has a nice example of what the shaders can do... " - is this unqualified, meaning you want to see and play with all kinds of shaders?

Playing with Poser shaders has become a seriously time consuming hobby for me. I am building shaders with many many nodes now on a regular basis.

The best one I've come up with is demoed in this attached image. This is 147 nodes. It implements a loom. See those little black-and-white insets? Those are the loom weave patterns. You can make those yourself or download them from the net. Then you load that image into my shader and it takes care of the rest, working out where the threads go and so on. The colors can be procedural or come from swatches - the shader makes it all come out right. In the end you can convert a render to a seamless tile, and toss the shader tree after that. And it can do plaids quite easily.

The hardest part was the fuzzies - it's not easy to get those right. 

I made a tool called Matmatic to do these giant shaders much more easily. It's been beta testing five months now.

If you want to learn more about how to do these, or just want to see some wierd stuff like Jessi as Goldfish, follow these links.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
