Point Light Properties

When rendering with V-Ray, the following parameters are supported:

Light

Intensity – The total energy that the light emits.

Light Color – The color that the light emits.

Intensity Units – Determines how the light's Intensity setting should be interpreted.

Source Radius – Radius of light source shape. Value of 0 will treat the light as Omni Light. Values greater than 0 will treat it as a Sphere Light.

Temperature – Specifies the color value of the light expressed in Kelvin.

Use Temperature – When enabled, the color of the light is specified by the Temperature value multiplied by the Light Color value.

Affects World – When enabled (the default), the light contributes to the lighting in the level. Disabling it will stop the contribution of the light in the environment.

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

Use Inverse Squared Falloff – Specifies whether to use the physically based inverse squared distance falloff.

Specular Scale – Multiplier on specular highlights. The value controls the light's contribution to specular reflections
