that's really good to know.  i saw that in the daz thread and was heartened to see a merchant try it, but slightly dismayed that she didn't know about it  before you posted. 

it's not a difficult trick to blend textures in poser.   there's what, 4 different nodes you can do it with?  blender, color ramp, math, color math... oh! and edge blend.  i'm far from an expert user, and here's my blend of rss-ified texture/hair texture and procedural marble.

i feel like i  shouldn't know more about how the textures they sell can be implemented in the target software than the merchants themselves. i'm no bagginsbill, no takezo, no olivier, no Ro.br.  and certainly no face_off. i basically feel my way through the material room.  but if the case is actually that they didn't know, despite the multiple threads showing how such things can be done, the multiple tutorials, the many bagginsbill matmatic threads, etc. then i guess this is a boon in the end.

and maybe i just know more than i think.
