Creating a Directional Light

To create a Directional Light, use the button in the V-Ray Lights tab. Select a point position in the viewport. If a list of input positions is connected, multiple lights are generated. The number of input positions determines the lights count.

The point position and target point combined determine the light orientation vector.
