Enable scattering fog – Enables scattering volumetric fog. Fog color – Specifies the color of the fog when it is illuminate by light sources. Fog distance – Specifies the fog density. Larger values make the fog more transparent, while smaller values make it denser. Fog transparency – Specifies the color of the volumetric shadows and the tint for the objects seen through the fog. Brighter colors make the fog more transparent, while darker colors make it denser at a distance given by the Fog distance parameter. Fog emission – Specifies the fog emission (self-illumination). You can use this parameter to substitute the ambient illumination inside the fog, instead of using GI. Fog height – Specifies the height of the fog in meters. Fog start – Specifies the distance from the camera at which the scattering fog starts. Fog end – Specifies the distance from the camera at which the scattering fog ends. Fog light boost – Specifies a multiplier for lights that affect the scattering fog. Fog max opacity – Specifies the maximum opacity of the scattering fog while keeping the "light shaft" effect. A value of 1 means the fog is completely opaque, while 0 means the fog is invisible. Affect secondary rays – Enables or disables the tracing of secondary rays through the volumetric. Scatter GI – When enabled, the fog also scatters global illumination. Note that this can be quite slow. In many cases, global illumination within the fog can be substituted with a simple emission term. Scatter only infinite direct lights – When enabled, the scattering fog is affected only by directional and sun lights. Texture mode – Specifies a texture mode to control the scattering fog's density. Available options are Off, Built-in smoke density, and From V-Ray scene. |
