Bruneton's Improved Atmospheric Scattering for Unity

A physically-based atmospheric skybox shader for Unity. Based on work by Eric Bruneton and Scrawk.

Requirements

This tool requires a graphics card that supports the following Unity features:

• Compute Shader
• Texture3D
• RenderTexture

Usage

1. Generating the atmosphere

1. Select "DSS/Atmosphere/Generate" from the menu bar.
2. Set the precomputation parameters as desired.
3. Press "Precompute".
4. Choose paths to save the generated material and textures.

2. Using it as a skybox

1. Select "Window > Lighting > Settings" from the menu bar.
2. Locate the "Environment" heading in the lighting window.
3. Drag generated material into the Skybox Material slot.
4. Drag your scene's main directional light into the "Sun Source" slot.

A note on color space

• For best results, ensure that your projects color space is set to linear, rather than gamma.
• If you are using the tonemap post-processing effect, then be sure to disable the tonemap checkbox on the material.
