The Fog object simulates the presence of atmospheric haze or mist in a scene. It adds depth and atmosphere by gradually reducing visibility in the scene and creating a sense of distance.
You can add a Fog object to a scene through Scene > Add Object > Fog, or by clicking the clouds icon in the Scene window.
Fog Settings #
You can customize Fog settings such as opacity, color, and distance to achieve various atmospheric effects.
| Setting | Description |
|---|---|
| Falloff | Selects the method for computing how much particulate matter is present along a given span of distance. “Exponential” is generally the most physically accurate, but “Linear” provides direct, simple control over falloff distance. |
| Color | The color of the fog medium. |
| Distance | Determines how far one can see objects through the medium. Behavior differs somewhat with the falloff function. |
| Max Opacity | This is the maximum occlusion the medium can provide, regardless of distance. |
| Dispersion | Sets the degree to which light scatters in the medium. This primarily affects sky illumination and directional lights. |
Illumination Settings #
The illumination settings of the fog allow you to control how the fog interacts with light sources in your scene.
| Setting | Description |
|---|---|
| Ambient / Sky | Mixes between a volumetric medium lit by the sky background, and a simple ambient color. |
| Lights | Controls the brightness of omni, spot, and directional light sources in the medium. |
