When disabled, the light does not cast shadows.Īffect Diffuse – When enabled, the V-Ray Sun affects the diffuse properties of the materials.Īffect Specular – When enabled, the V-Ray Sun affects the specular of the materials.Īffect Atmospherics – Specifies whether the light influences the atmospheric effects in the scene.

Shadows – When enabled (the default), the Sun casts shadows. This is useful to prevent bright speckles on glossy surfaces where a ray with low probability hits the extremely bright Sun disk. Invisible – When enabled, the sun becomes invisible to both the camera and reflections. Horizon Offset– Allows the user to manually lower the horizon line. Values close to 0.0 produce a sharper horizon line, while larger values produce a softer horizon line. Ground AlbedoĪlbedo Color – Sets the ground color of the V-Ray Sun and Sky system.īlend Angle – Specifies the angle in degrees where blending occurs between the horizon line and sky. This parameter is inactive when the Sky Model is set to PGR.

Values closer to 0.0 make the sunlight yellow, and values closer to 1.0 make it blue. Turbidity – Determines the amount of dust in the air and affects the color of the sun and sky. Smaller values produce a clear, blue sky and sun as seen in rural areas, while larger values make them yellow and orange as seen in big cities. This parameter is inactive when the Sky Model is set to PGR. Horizon Illum. – Specifies the intensity (in lx) of the illumination on horizontal surfaces coming from the sky. PRG Clear Sky – V-Ray Sky procedural texture is generated based on the PGR Clear Sky method which has enhanced sunrise and sunset sky. Hosek et al – V-Ray Sky procedural texture is generated based on the Hosek et al. method.ĬIE Clear – V-Ray Sky procedural texture is generated based on the CIE method for clear sky.ĬIE Overcast – V-Ray Sky procedural texture is generated based on the CIE method for cloudy sky. Preetham et al – V-Ray Sky procedural texture is generated based on the Preetham et al. Sky Model – Specifies the procedural model that is used to generate V-Ray Sky texture. This includes the appearance of the sun disc as seen by the camera and of the reflections, as well as the blurriness of the sun shadows. Size Multiplier – Affects the visible size of the sun.

Intensity Multiplier – Affects the brightness of the sun and can be used to reduce the default brightness. The intensity of the light still depends on the position of V-Ray Sun in the sky. Override – Sets the color of V-Ray sun to the color in the Filter Color parameter. Instead, intensity is controlled through the Intensity Multiplier. The intensity of the light no longer depends on the position of V-Ray Sun in the sky. Color and IntensityĬolor – Shifts the hue of SunLight system towards the color specified in the field.Ĭolor Mode – Affects the way the color in the Filter color parameter affects the color of the sun.įilter – Shifts V-Ray sun's hue according to the Filter Color parameter.ĭirect – Sets the color of V-Ray sun to the color in the Filter Color parameter. Vertical Angle – Controls the custom sun altitude angle (vertical rotation). Horizontal Angle – Controls the custom sun azimuth angle (horizontal rotation). Custom OrientationĬustom Orientation – Enables custom orientation. The opacity texture is still filtered as normal.Enabled ( ) – Turns SunLight on and off. This mode reduces lightning calculations but might introduce some noise in areas where the opacity map has gray-scale values. Stochastic – (Optimal) The surface is randomly shaded as either fully opaque or fully transparent so that on average it appears to be with the correct transparency. This is the fastest mode but it may increase flickering when rendering animations. This mode also disables the filtering of the opacity texture. If there is no texture in the source slot, the option is ignored.Ĭlip – (Very fast) The surface is shaded as either fully opaque or fully transparent depending on the value of the opacity map (i.e. Opacity Texture Alpha – The opacity texture alpha channel controls the opacity, instead of the default texture intensity. Diffuse Texture Alpha source works the same way as Diffuse Map Alpha as Transparency legacy option from the V-Ray versions before 3.60. A texture map can be assigned to this channel.Ĭustom Source – When enabled, V-Ray uses an alpha channel to control the material opacity.ĭiffuse Texture Alpha – The diffuse texture alpha channel controls the opacity. Opacity * – Specifies how opaque or transparent the material is.

Some options are available only in Advanced mode.
