Quote - on the sari silk

they use a very thin silk thread (usually fairly high gum) and often it is a brocade weave with a strong colored thread one way and a silver or gold thread the other. the pattern is woven in.  The side effect is that folds and shadows where the fabric changes angle the metallic threads show through

I've also seen it done in contrasting colors, but not usually on sari fabric.  I've seen some nice shot silk and duipionis that show blue/pink or green/red depending on angles

I think you might get that shimmerred beaded effect by looking at the visual effect of small clear glass or silver rocaille beads scatterred on a solid base.  The beads themselves are very small, so would not be all that evil to simulate on a shader.

Another option is silver or gold threadwork - though how you can do that via shader and not have simple straight lines I think on BB can tell us :)

BB those rhinestones look fantastic.  I'm almost tempted to make you a double layered gown just for that shader.

Thanks for the info, Lyrra. That explains why sari silk is so gorgeous. But that's way beyond my skill to replicate in the material room. ;)
