Procedural Universe is a generator that allows users to create customizable space elements directly within Blender. The tool provides a unified interface for assembling scenes with planets, stars, galaxies, black holes, nebulas, and asteroids. Built using a combination of Geometry Nodes and shader networks, it offers both image-based and fully procedural generation techniques.

The add-on includes built-in render settings adjustments and a randomizer function to quickly iterate on different styles. Users can save and load custom space configurations using the integrated preset system. Additional features include an atmosphere setup that reacts to specific light directions and automated tools for configuring multi-layer EXR rendering.
