Instantly I came across pictures of everything except Lycra cloth, lol. So, with that in mind, I attempted to find any photos that showed the 3d structure of the weave, to attempt to reproduce a bump-map for the weave. So there is not single Spandex weave, and mo single type of 'Spandex', lol. Now this is where it gets very interesting, Lycra is NOT used by it's self in cloths, it is combined with other thread material to make the thread that makes the cloths. That apparently was just an illusion of how light was scatted in an almost speckle like way off of the thread structure of the Lycra. At first I had seen photos of the stuff dry, and it had a almost Gaussian like speckle patron to it, almost like Granite (Schist). So, as for Lycra (or spandex), that has been a considerable learning experience for me. Something that the DazDefaultShader alone is going to have an incredibly difficult time reproducing without some incredibly high-definition displacement maps, and that is just not going to happen at all unless the render is also high enough for TDL make to not just blur the 'texel's all together into a smooth surface, lol.

As you can clearly see in thee photo, the cloth weave fibers are incredibly small, and have distinct directionality to the 'Velvet' and 'Gloss' effect. Like the attached photograph of a spool of Carbon-fiber cloth. Nothing against all the shaders that do replicate the visual effect of cloth, this is more an exercise in replicating the actual cloth weave at the almost microscopic level, to better capture that 'Velvet' effect with some cloth that has a kind of polar aspect to it. Trying to replicate the fine detail texture of Lycra, to go with the HD craze. Lets see if this gives ma a new page, as this is a change of gears in a minor way (no worry if not).
