⭕️ Tons of powerful features

Physically based:

Our volumetric lighting and fog accurately renders atmospheric particles and light scattering using algorithms described in leading technical papers and strategies from major AAA studios.

Volumetric Lighting and Shadow:

Objects realistically occlude lighting by interacting with the fog, keeping your fog grounded in your scene.

Fast:

Optimized, high-performance rendering with intelligent depth-aware upscaling (~0.2ms on an Nvidia 1080 desktop equivalent).

Volumetric Noise:

Built-in customizable volumetric noise gives texture to the particle distribution. Choose from 5 configurable volumetric noise styles or import your own texture for the ultimate control.

Atmospheric Height Fog:

Particle density exponentially decreases over height, resulting in realistic fog attenuation over altitude. Control the fog height as well.

Long-Range Visual Consistency:

Toggleable analytic height fog can be rendered behind local volumetric fog to guarantee visual realism over long distances.

Stylized Fog Options:

Achieve your artistic vision with color ramps, simple color adjustments, and light and shadow intensity sliders.

Additional Lights:

Illuminate the fog with volumetric point lighting.

Fog Density Masks:

Add or erase volumetric fog using Fog Density Masks

Temporal Anti-Aliasing:

Improved quality for high-density fog with optional Temporal Anti-Aliasing.

Integrated with the Volume Component System:

Seamlessly tie Volumetric Fog into your workflow with Unity's Volume Component system. Set Global Fog parameters and local Box and Sphere Volume parameters with seamless blending between Fog Volume settings.
