Asteroid Belts

Overview

Feature	Description
Asteroid Shader	Shader Graph with vertex displacement for procedural shape and moon surface procedural normals for rocky appearance. Per-instance unique ID generation to produce unique asteroid shapes within an asteroid belt.
Asteroid Belt Component	Belt procedural generation - belt torus shape settings, asteroid color palettes and random generation. Handles edit mode and runtime rendering through instancing. Performance optimization via mesh LOD system, frustum culling.

Asteroid belts use a custom procedural shader with vertex displacement instancing to render 1000s of instances dynamically at runtime with good performance.

Quick Start

To add a new asteroid belt to your scene, use the custom menu item to automatically set up the asteroid belt with material, scripts and LOD meshes. Right click inside your scene hierarchy to open the context menu and select "Parallel Cascades > Asteroid Belt".

This will create a game object in your scene with the Asteroid Belt component. Here you can adjust the whole asteroid belt appearance and animation - inner and outer radius, instance count and size ranges, animation speeds (orbit/rotation).

To edit the appearance of asteroids - colors, surface normals, craters, displacement strength, you can adjust the asteroid material which is embedded in the Asteroid Belt inspector:
