Precomputed Atmospheric Scattering for unity

Aerosol

This project implements a simplified version of Precomputed Atmospheric Scattering in Unity.

Usage

The Scenes/Demo contains a simple working example. To use this skybox, follow these steps:

• Drag the prefab in Prefabs/AerosolSkybox into your scene for texture pre-computation.
• Assign the material in Materials/Skybox as the skybox material. Also, remember select your sun source in the same tab.
• In the script context menu, use GenHeader tab to re-generate header.hlsl for different atmosphere parameters.

Now you can play with the skybox material. If you want more control of the atmosphere parameters, modify the values in Prefabs/AerosolConfig.asset, then use the context menu GenHeader to re-generate the header file Shaders/header.hlsl which provides atmosphere constants for shaders.
