Procedural Planet Generation Demo

Procedural Planet Generation is a Unity framework for creating procedural celestial bodies through shaders with editor tools for texture baking and scripts for in-editor and runtime procedural generation. Generate stars, gas giants, asteroid rings, moons, and Earth-like planets with customisable properties and randomization ranges.

Built with Shader Graph, VFX Graph, and Render Graph, this framework creates beautiful and detailed, lightweight, non-landable planets optimized for viewing from space. This is NOT a terrain generation tool for landable planets - it focuses on procedural surface shaders, texture generation, and visual effects rather than geometric terrain, mesh generation, or raymarching. It's perfect for space strategy games, solar system maps, background environments, and skyboxes.

This demo project contains three space scenes where you can fly around and view procedural planets individually or in a small simulated solar system. You can generate new bodies instantly at runtime.
