Input Parameters
...
On (Boolean) – Enables or disables the light source.
...
Intensity (Number) – Provides an option to control the light source intensity. Calculated in Default (Scalar) unitsCalculated in the specified units.
Intensity Units (Integer) – Specifies the light unit of measurement. Using correct units is essential when working with physical camera exposure. The light automatically takes the scene units scale into consideration to produce correct result for the scale being worked in.
Default (Scalar) – The color and multiplier directly determine the visible color of the light without any conversion. The light surface appears with the given color in the final image when seen directly by the camera.
Luminous Power (Lumens) – Total emitted visible light power measured in lumens. The intensity of the light does not depend on its size. A typical 100W incandescent light bulb emits about 1500 lumens of light.
Luminance (lm/m^2/sr) – Visible light surface power measured in lumens per square meter per steradian. The intensity of the light depends on its size.
Radiant Power (W) – Total emitted visible light power measured in watts. The intensity of the light does not depend on its size. This is not the same as the electric power consumed by a light bulb. A typical 100W light bulb only emits between 2 and 3 watts as visible light.
Radiance (W/m^2/sr) – Visible light surface power measured in watts per square meter per steradian. The intensity of the light depends on its size.
Invisible (Boolean) – Makes the light source invisible. It does not affect the light source's illuminance.
Radius (Number) – Controls the size of the light source. Light intensity and shadow softness depend on the size. Bigger size leads to softer shadows and stronger illumination. Multiple Radius values can be used here. The number of Radius values does not affect the lights count.
Output Parameters
...
Add Light (Generic Data) – Light output that can be connected to a V-Ray Render component.
Example
...
Example
...
...
Sphere Light Light component connection. Note the toggled off Simple Light Rig plugged used as an override. If there is no Light Rig input in the V-Ray Render component it will always internally create one.
