Sun light

Enabled – Turns on and off the sun light.

Color – Changes the color of the sun and depends on the Color mode parameter.

Intensity – Specifies the intensity of the sun and can be used to reduce the default brightness. 

Sun size mult. – Controls the visible size of the sun disc. This value can be used to control shadow softness cast from objects. Lower values produce sharp shadows while large values produce softer shadows. 

Color mode – Affects the way the color in the Color parameter affects the color of the sun.

Filter –  Shifts the hue of the sun towards the color specified in the Color parameter. 
Direct – Sets the color of the sun to match the color in the Color parameter. In this case the intensity of the light does not depend on the V-Ray Suns position in the sky and is controlled through the Intensity parameter. 
Override – Sets the color of the sun to match the color in the Color parameter but the intensity of the light still depends on the sun's position in the sky.

Sky model – Specifies the use of location coordinates, date and time of day to control the sun position.

Preetham et al. – The sky procedural texture is generated based on the Preetham et al. model.
CIE Clear – The sky procedural texture is generated based on the CIE method for a clear sky.
CIE Overcast – The sky procedural texture is generated based on the CIE method for a cloudy sky.
Hosek et al. – The sky procedural texture is generated based on the Hosek et al. model.
PRG Clear Sky – The sky procedural texture is generated based on the PRG Clear Sky model which has enhanced sunrise and sunset sky.

Ground albedo – Sets the color of the ground.

Indirect hor illum – Specifies the intensity (in lx) of the illumination on horizontal surfaces coming from the sky. This parameter is enabled when one of the CIE Sky Models(CIE Clear, CIE Overcast) are selected.

Blend angle – Specifies the angle in degrees where blending will occur between the horizon line and sky. Values close to 0.0 produce a sharper horizon line, while larger values produce a softer horizon line.

Horizon offset – Allows the user to manually lower the horizon line.

Turbidity – Determines the amount of dust in the air, which in turn affects the color of the sun and sky. Smaller values produce a clear, blue sky and sun similar to what is seen in rural areas, while larger values make the sun and sky more yellow and orange.

Ozone – Affects the color of the sun light. Available in the range between 0.0 and 1.0. Smaller values make the sunlight more yellow, while larger values make it bluer.

Invisible – When enabled , makes the sun invisible, both to the camera and to reflections. This is useful to prevent bright speckles on glossy surfaces where a ray with low probability hits the extremely bright sun disk.

Shadows – When enabled (the default), the light casts shadows. Turn this option off to disable shadow casting for the light.

Shadow bias – The value moves the shadow toward or away from the shadow-casting object(s). Higher values move the shadow toward the object(s), while lower values move it away. If this value is too extreme, shadows can "leak" through places they shouldn't or "detach" from an object. Other effects from extreme values include Moire patterns, out-of-place dark areas on surfaces, and shadows not appearing at all in the rendering.

Diffuse – Determines whether the light affects the diffuse portion of the materials. The value controls the light's contribution to the diffuse portion of the materials.

Specular – Determines whether the light affects the specular portion of the materials. The value controls the light's contribution to specular reflections.

Reflections – Specifies whether the light source appears in reflections.

Background 

Mode – Specifies the mode which will be used for the background. Note that the Background texture is not used for lighting and glossy reflections.

Same as environment – Uses the specified Environment source.

Solid color – Uses a solid color for the background.

Color – Specifies a color as a background.

Image – Uses an image as a background.

Color – Specifies a color as a background when Background Image is empty.

Load background – Specifies an image to use as a background.

Mapping – Specifies the mapping method for the image - spherical or screen.

Rotation – Specifies a rotation angle in degrees for the background image. 

Intensity – Specifies the intensity for the background image/color.

Use for refraction/mirror reflection – When enabled, the background override is used for both refraction and perfect (glossiness=1) reflection rays.
