Procedural Celestial Body Materials Introduction

This asset contains a set of procedural materials and scripts you can use to generate gas giants, asteroid rings and stars, and stylize them with post-processing glow effects.

Asset Contents

1. Shader Graph Procedural Shaders and Materials, MonoBehaviour scripts for quick setup of:

   • Procedural Asteroid Ring
   • Procedural Gas Giant + Lit Atmospheric Glow Effect
   • Procedural Star + Star Corona Glow

2. Premade Celestial Body Prefabs - 3 Stars and 6 Gas Giants

   • Seen in the example image above, these are ready to drop into your scenes.

3. Utility Editor Scripts

   • Editor Menu Items to create procedural celestial bodies with all materials, textures, and components assigned and ready to edit.

4. Custom 3D Meshes for celestial bodies

   • icosphere_high - high-poly sphere for rendering smooth stars and gas giants. High triangle and vertex count allow for smoother looking dynamic procedural visuals.
   • double_sided_plane - double-sided plane mesh allow for Asteroid Rings to be viewed from both sides.

Installation

The assets for the 3D gas giants and stars are stored in a separate folder, as they are currently being distributed as a free asset on the asset store. They are included in the paid Procedural Space Skybox Asset, and do not require a separate download.

Samples

There are two sample scenes in this asset:

• Space Objects Sample Scene - shows the 9 sample celestial bodies, with glow effects and URP settings.
• 3D Skybox Sample Scene - shows a more complex 3D Skybox set up using some of the celestial body prefabs.

URP Settings

The Sample URP Asset and Renderer have the shadows and anti-aliasing settings used to get the look of the asset presented in the store page.

The 3D Skybox Renderer is needed for 3D Skybox setup.

VSync

To avoid screen tearing with the glowing corona post-processing effect, make sure to enable VSync in the Scene View:

And in Builds, from the Project Settings:
