A little exposition first. I'm terrible with textures. So much so that I usually just give my models a diffuse color and that's it. I feel fine with doing that with freebies, but it's really not a practice I want to continue , especially if I ever start selling as a vendor. Besides most of the time the color is just flat. Now, I think a shader would be better, so I'm trying to learn matmatic so I can do that.

So...

1. I know I've see Baggnsbill do shaders that have stripes and sequins, so my question is, can Matmatic do plaid shaders as well? And just how would one go about doing it?

2. Are nodes for the material room created through scripting or is there some button or submenu somewhere that I can't find that creates them?

3. Is there a good and FREE text editor for the Mac that work's okay for scripting python?

(Edit)4. Also, I can't seem to download Bagginsbill's sequins shader. Anybody know if that is still available?
