The first nylon shader I posted was a "second skin" style dual material that was nylon on skin.

If you have an actual clothing prop, you want to use the newer BBNylon shader I posted. I'm linking you to page 5 where the matmatic script can be found, as well as the a second-skin version as an mt5 by Anthanasius.

The other 4 pages detail how I made it from first principles, geometry, the physics of translucent fibers, and math. You don't need to know the math to use it.

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)
