Quote - That's what I'm hoping. I was initially hoping to get matmatic working so I can do some of this myself in the future. I don't know whether I'm just not following the instructions right or because they seem to be written for Windows and I'm on a Mac, which I didn't think would make any difference with Python, or what.

So I thought I'd go with plan B.

I'm happy to help in either way. I can give you a plaid shader, or I can help you make them (should happen in another thread, however).

Did you want the blue one I made like your post?

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)
