Procedural Planet Generation - Lite: Baked Planets and Simple Procedural Shaders

This is a free, lightweight version of the Procedural Planet Generation framework.

📚Check out the online Documentation.

This framework is NOT for landable planets - it uses shaders and procedural textures to be viewed from orbit or solar system maps.

🚨 New Update:

3.1.0 - January 2026: We added 12 new sample planets, baked from Procedural Planet Generation - with colors, normals, specular, and emission. A new custom lighting demo scene shows a basic setup of the omnidirectional shader lighting pipeline in the full asset. New gas giant and asteroid ring shaders.

🪐 Fully Procedural Shaders

• Moons
• Earth-likes
• Gas Giants
• Asteroid Rings
• Atmospheric Glow effect for earth-likes and gas giants.
• Stars
• Corona glow effects for stars.

✅ Easy to use

These shaders are built with Shader Graph and the post-processing effects use RenderGraph, but no shader programming knowledge is required to use this asset. It's ready to use out of the box with utility editor menu items and MonoBehaviour scripts that allow you to quickly create procedural celestial bodies with pre-assigned materials, textures, and components ready for editing.

For advanced users, all shaders are built with modular components split into Shader Graph sub-graphs and .hlsl scripts, neatly organized to facilitate easy extension and modification.

🌌 Static Skybox Included

A high-quality stylized 4K skybox generated from the Procedural Space Skybox asset is included in the samples.

⚡Upgrade for more

The Procedural Planet Generation pack adds:

• Earth-like planet heightmaps and normals: Procedurally generated normals for land-sea coast heights, rough terrain surfaces and mountains. Heightmap color blending for natural-looking terrain coloration.
• Earth-like dynamic clouds and city lights on the dark side of planets.

• Moon heightmaps and normals: Procedural normals for craters and ridges.
• Whirling storms for gas giants.
• Enhanced transparency based on ring banding and density variation for more natural-looking ring structures.

• Static texture baking editor tools: Editor-based color and heightmap to cubemap baking utilities allow you to convert fully procedural shaders into optimized static textures with one-to-one visual parity. Automated in-shader switching between cubemap sampling and procedural textures.

• Custom shader lighting implementation for omnidirectional space lighting.
