I wasnt sure how to acheive that while keeping the total number of textures low. My thought process was to do it like that, id need individual textures for every book and I feel like thats just too many textures for some books.
The way I was using em was to use 4 brushes to make a book. One for each cover, the paper and spine.

First texture, btw, so Im definitely open to all kinds of input. At some point after I finish this map, I plan on using these textures to build a breakable bookshelf or two. an explosion of paper, wood, and bits of books. Too much workload for right now, though.
