Konrad Kaca used Blender's Geometry Nodes to make artists' lives a little simpler: he released Book Stacks Generator, a tool that will put your 3D books naturally on top of each other – for free!
The generator can randomly place and rotate books, flip and stack them. It offers randomized UVs using an atlas texture for different book covers, vertical and horizontal stack modes, and a quick way to fill shelves, desks, or any other containers.
