Personally, I use the weave node in demonstrations because everybody has it, but I don't use it in practice. Few fabrics are woven that way and when I use it everything has the look of bandages.

Twill is much more realistic. Blue jeans are twill. Oxford shirts are twill.

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)
