This page provides information about the Light Rig Sun System in V-Ray for Grasshopper.
Overview
The Light Rig Sun System includes a V-Ray Sun Light and Sky texture plugged in all environment slots.
The Sun direction is visible in the Rhino viewport.
Input Parameters
On (Boolean) – Enables the Sun Light. Note that disabling the Sun does not disable the Sky texture and the set is still illuminated.
Position (Point) – Controls the point position of the Sun. Keep in mind that the Sun is always infinitely far away (it's a directional light source). The Position combined with the Target determines the Sun direction vector. If there is no target specified it is automatically placed in the world origin.
Target (Point) – Controls the point position of the Sun target.
Intensity (Number) – Controls the intensity of the Sun light.
Filter Color (Color) – Tints the automatic Sun light color. Note that Sun light color also depends on its altitude.
Ground Color (Color) – Provides a connection slot to the Ground Albedo Color.
Caustics Radius (Number) – Defines the area around the V-Ray Sun from where the photons will be shot.
Caustic Subdivs (Integer) – Determines the number of caustic photons emitted from the light source. Lower values equal noisier images for less render time. Higher values produce smoother images for longer render time.
A preview of the photon emission disk is visible in Rhino's viewport.
Output Parameters
Light (Generic Data) – This Light output should be connected to the V-Ray Renderer's Light input slot.
Env (Generic Data) – V-Ray Environment to be connected to the V-Ray Renderer's Environment input slot.

- Loading Rig components from projects created with V-Ray 6.10.00 into newer versions, requires parameter rewiring.
