FogOptions

Fog's color used for ambient light in-scattering. A good value is the average of the ambient light, possibly tinted towards blue for outdoor environments. Color components should be between 0 and 1; values above 1 are allowed but could create a non energy-conservative fog. Used as a tint when fogColorFromIbl is enabled. Default: white.

Extinction factor in 1/m at the fog height. Controls how much light is absorbed and out-scattered per unit of distance. Each unit of extinction reduces incoming light to 37% of its original value. In linearFog mode, this is the slope of the linear equation if heightFalloff is 0. Default: 0.1.

How fast the fog dissipates with altitude. heightFalloff has a unit of 1/m. It can be expressed as 1/H, where H is the altitude change in world units m that causes a factor 2.78 (e) change in fog density. A falloff of 0 means the fog density is constant everywhere. Ignored in linearFog mode if set to 0. Default: 1.0.

Optional sky texture (mipmapped cubemap) for fog color sampling. When provided, the fog color will be sampled from this texture, with higher resolution mip levels used for objects at the far clip plane and lower resolution mip levels for closer objects. fogColorFromIbl is ignored when this is specified. In linearFog mode, mipmap level 0 is always used. Default: null.
