I will even reduce the matter to the main problem shader.  It is a "special effects" shader, which seems to be a class of shaders which is casually shrugged aside when these discussions turn to any problems or frustrations involved with Poser GC.  "Some shaders don't convert," I say.  "Sure they do," everyone replies.  Snarlygribbley has a tool.  Switch your grey maps to a new gamma.  Voila!  But it is not so simple.

I just need a flexible lurex shader in Poser.  There are others, but this is the main one.  I am a simple person.  Poser appeals to me for a narrow range of reasons.  I like to endlessly tweak and adapt and rework the same characters.  I am not very good at most of this stuff involved with 3D.  I can follow BB's math only when he provides liner notes.  I can make a "correct" shader from a clearly-explained recipe.  Fair enough.  But I've had some small margin of success with my favorite characters, and I am more interested in using them than in using GC.  To use the characters, I need to adapt a special case shader for GC.  How?  No one seems to know.  I don't.  I have tried, others have tried.  It doesn't even need to be fully "correct".  I don't really want a reflective shader.  I just want one that looks more or less like what I show in the attached.  It renders quickly and looks more or less like what I need.

Lurex is a fabric which has reflective metal fibers woven in, which causes it to change color at different angles and in different light, as well as look "sparkly".  I have done my best to recreate it.  Doing so for GC hasn't worked so far.  Why?  Who knows?  I don't.  The experts are strangely silent, when I bring up the topic.  Could it be that Firefly and GC have limitations we don't like to discuss?  Maybe?  I speculate, perhaps unfairly.  Ahem.

The shader is pictured here.  Yes, I am a geek and a goofus, but this is my reason for enjoying Poser.  :lol:

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
