Making material and L.I.E

Smartest Idiot

Hopefully, I am putting this in the right place.

I'm looking for tutorial and best practices on how to make custom material and L.I.E. for different things in Daz. I don't care if it is paid or free, I'm just looking for something that goes in enough depth that should I throw a curveball at the situation. IE: using Microsoft paint instead of photoshop ( no I'm not doing that but that should get my point across) I would be able to work with it.
