This page provides information about the Light Sphere in V-Ray for Grasshopper.
Overview
V-Ray Sphere Light node creates a sphere light source. It can be connected to the V-Ray Render which automatically adds it to the rendered scene. If a list of input Positions is connected to this component multiple lights are generated. Multiple Radius values can also be used. The Number of Instances tag at the bottom of the node indicates how many times the object is currently being instanced. The number of input positions will determine the lights count. The number of Radius values will not affect the lights count. |

Input Parameters
On (Boolean) – Enables or disables the light source.
Position (Point) – Sets the light source point position. If a list of input Positions is connected multiple lights are generated. Note that the number of input positions determines the lights count.
Color (Color) – Provides a slot to set a light source color.
Intensity (Number) – Provides an option to control the light source intensity. Calculated in Default (Scalar) units.
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 node.
Example
Sphere Light node 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.
