Page Contents

 

Overview

A Sun light is a spherical light source placed at a specific location which simulates the sun in the sky. Developed to work together, the VRaySun and Sky reproduce the real-life Sun and Sky environment of the Earth. Both are coded so that they change their appearance depending on the Elevation and Azimuth of the Sun disk.

 

 

The VRaySunAndSky Blueprint Actor is accessible through the Modes panel by searching for VRaySunAndSky or from VRayForUnreal > Content > BP > Actors > VRaySunAndSky in the Content Browser Tree. Select the Blueprint and drag and drop it in the level.
