sorry, it's going to take longer than expected.
I started to build this as a Word .doc so it would be easier to read, but it crashed and ruined the file. I lost most of the beginning of the file, but nothing that's not fixable.
it's just that I hate to rebuild something that came up "in the moment". I'm no more in that "moment" so it won't be the same. I'll see what I can come up with.
EDIT: it's coming along. I'm including some UVW mapping explanations too. it's looking like a "mapping for dummies" kind of tutorial, but I think I covered most of the hard parts.
