Stylized procedural planet and solar system creation tool ready for Unity 6.

With its custom physics-based atmosphere shaders, its seed-driven procedural planet generator and its Keplerian orbital mechanics, you have everything you need to bring your next cosmic scene to life.

🪐 Types of planets (random generation or preset selection)

• Rocky Worlds — vibrant continents, oceans, and rich biomes inspired by habitable planets

• Ocean Worlds — heavy water coverage dotted with beautiful tropical archipelagos

• Desert Worlds — sun-baked dunes, copper horizons, and dusty cloud sheets

• Glacial Worlds — frozen seas, cyan ice sheets, and pale misty horizons

• Lava Worlds — dark basalt crusts split apart by blazing magma rivers under a blood-red sky

✨ Features

• Vibrant Low-Poly Planets — subdivided icosphere, multi-layered Simplex noise, 100% textureless

• Physics-Based Raymarched Atmosphere — Rayleigh & Mie scattering, biome-dependent sky colors, solar halos, accurate planetary occlusion

• Keplerian Solar Systems — real orbital mechanics, inclination, eccentricities, synchronous moons, HDR plasma star with custom crown

• Whittaker Biome Blending — organic terrain and color distribution based on Altitude $\times$ Moisture matrices

• Real-Time Terraforming — runtime voxel-like digging and terrain sculpting directly through the camera view

• Procedural Cloud Layers — dynamic, animated custom cloud shaders with slow, textureless wind drift

• Adaptive 6-DOF Freecam — scroll-wheel velocity scaling from fine ground details to interplanetary cruise speeds

• Deep Space Backdrop — fully procedural skybox featuring Voronoi starfields and deep two-tone nebula dust

• Smart Scatter System — automatic rock and vegetation placement utilizing slope, altitude, and density filters

• Dynamic Editor Wizards — Quick "Create Planet" and "Create Star System" custom tool windows with manual or auto modes

• Ultra Lightweight — zero external dependencies, assembly definitions included, tiny runtime memory footprint
