Analytic Fog

Analytic Fog strikes the perfect balance between Unity’s built-in fog and full volumetric solutions. This asset offers a greater visual quality and artistic control than the standard fog, without the complexity, performance cost, or integration overhead of true volumetrics. It is an ideal choice for stylized and semi-realistic projects that prioritize art direction over physical accuracy.

✅ Key Features:

- Supports both uniform and height-based fog models with smooth exponential attenuation.

- Affects skybox for a fully cohesive look (optional).

- Stable, artifact-free rendering with no stochastic noise, ghosting, or flickering.

- Lightweight implementation with predictable, constant performance cost.

- Seamless integration with Unity’s Volume framework for clean, intuitive setup.

- Designed to work out of the box without conflicts with other assets.

- Supports orthographic projections, XR, MSAA, and all Rendering Paths.

- Includes a demo scene with a ready-to-use example configuration.

❌ Limitations:

- Unaffected by scene lighting. The fog color and appearance are controlled fully by the user.

- You can't place "fog zones" in the scene. The fog is only controlled by global or local post processing volumes.

- No advanced volumetric features such as 3D noise scrolling or god rays by design.

- No oblique projections support (custom portal/planar reflection cameras).
