A simple book generator for bookshelves or desks. There are two nodes, one for a single book and one for a collection of different books. Depth and height can be random, but not the width. The rotation uses the x-axis of the book; the random rotation rotates individual books at a random amount. The book's position helps center the book after the random rotation. The bookends on either side can be turned on/off, and their position can be fixed. To make multiple lines of books, duplicate them in the editor mode.

This includes some simple books and bookends, but they can be easily swapped for your books and bookends.

Steps to add a custom book cover;

1. Create or find an image that has the book spine and face.
2. Go to the Shader Window. Delete the texture node connected to the Color of the Principled Bsdf.
3. Connect an image texture node to the Color and have the UV of the Texture coordinate connect to the node.
4. Go to the UV Editing Window and fix the faces of the book model.
