Overview


Lighting your scene can be set using the standard Unreal Lights or the additional Blueprints that were created to emulate some of the unique V-Ray Lights.

 

Types of Lights



You can create native Unreal lights and V-Ray specific ones using Modes panel by using the search bar or from the Lights and V-Ray Assets categories and drag and drop into the level.

 

Unreal Engine Lights


V-Ray for Unreal supports some of the standard Unreal lights:

Directional Light – The Directional Light simulates light that is being emitted from a source that is infinitely far away. For more details on its functionality and use, see the Directional Light documentation.

Point Light – A Point Lights emits light in all directions from just a single point in space. For more details on its functionality and use, see the Point Light documentation.

Spot Light – A Spot Light emits light from a single point in a cone shape in a set direction. For more details on its functionality and use, see the Spot Light documentation.

Rect Light – The Rect Light emits light into the scene from a rectangular plane with a defined width and height. For more details on its functionality and use, see the Rectangle Light documentation.

V-Ray Lights


V-Ray for Unreal ships with some Light Blueprints: 

V-Ray Light Dome – A dome light (also considered an area light) creates light within a dome or spherical shape to create a traditional global illumination setup. This Light is frequently used to load HDRI environment images. For more details on its functionality and use see the V-Ray Light Dome Blueprint documentation. 

V-Ray Light Mesh – A Mesh light creates a light source from an object's surface area. For more details on its functionality and use see the V-Ray Light Mesh Blueprint documentation. 

V-Ray Light Rectangle - A V-Ray specific light source object that can be used to create physically accurate area lights of different shapes. For more details on its functionality and use see the V-Ray Light Rectangle Blueprint documentation. 

V-Ray Sun and Sky – A Sun light is a spherical light source placed at a specific location which simulates the sun in the sky. For more details on its functionality and use see the V-Ray Sun and Sky Blueprint documentation.
