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. 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. CIE Overcast – V-Ray Sky procedural texture is generated based on the CIE method for cloudy sky. CIE Clear – V-Ray Sky procedural texture is generated based on the CIE method for clear 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. See the Intensity Multiplier example below. 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. Direct – Sets the color of V-Ray sun to the color in the Filter Color parameter. Color – 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.
