Sun – Specifies the V-Ray Sun object in the scene that the Aerial Perspective effect is connected to.
Distance – Specifies the distance, in meters, at which the fog has absorbed 90% of the light coming from objects behind it. Lower values make the fog appear more dense, while larger values reduce the effect of the aerial perspective.
Height – Controls the height of the atmosphere layer, in meters. Lower values can be used for artistic effects.
Inscattered Light – Controls the amount of sunlight scattered from the atmospheric effect. The default value 1.0 is physically accurate; lower or higher values could be used for artistic purposes.
Filter Color – Specifies a filter color for the fog. Note that the fog color depends on the color of the sky.
Affect Environment – When Disableddisabled, the atmospheric effect is applied only to camera rays that hit actual objects, but not to rays that hit the sky. This is because the VRaySky V-Ray Sky texture already takes into account the amount of scattered sunlight. However, it is possible to enable this option for artistic effects, especially with low visibility ranges.
Affect Background – Specifies whether the effect is applied to camera rays that hit the background (if a background other than VRaySky V-Ray Sky is used). This option is enabled by default, but some interesting effects are possible when disabled.
Affect Alpha – Specifies whether the aerial perspective affects the Alpha channel.
Primary Visibility – When disabled, the effect appears perfectly transparent to camera rays.
