This page provides information about the Light Directional in V-Ray for Grasshopper.
Overview
The V-Ray Directional Light is a V-Ray specific light source plugin that can be used to create physically accurate area lights. It can be connected to the V-Ray Render component or any V-Ray Light Rig which automatically adds it to the rendered scene.
Input Parameters
On (Boolean) – Enables or disables the light source.
Position (Point) – Light source location (point position). If a list of input Positions is connected multiple lights will be generated. The number of input positions will determine the lights count.
Target (Point) – The Directional light Position and Target combined determine the light orientation vector.
Color (Colour) – Light source color.
Intensity (Number ) – Light source intensity. Calculated in Default (Scalar) units.
Shadow Softness (Number) – Sets the shadow softness. Zero (0.0) makes the shadows perfectly sharp, larger values produce blurrier shadows.
