This page provides information on the V-Ray Light Dome Blueprint.

Table of Contents


 

 

Overview

The V-Ray Light Dome is a light that casts light inwards at the scene as if from a spherical or hemispherical light source outside the extent of the scene. This light is frequently used for Image-Based lighting using panoramic HDR images for environments

 

 

 

For your Dome light to work properly with Dome Tex at render time make sure your texture has a valid file path (Source File in the texture Details panel). V-Ray loads the texture from that directory during rendering. If the texture is not found at the specified location the dome light will not contribute to the lighting and the scene will render black.

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

 

 

 

For the VRayForUnreal folder to be visible, you first need to enable Show Engine Content and Show Plugin Content in the View Options of the Content Browser.


 

 

When creating VRayLightDome in Unreal make sure its location is set to 0,0,0; rotation is set to 0,0,0 and scale is set to 1,1,1. Also make sure you have only one VRayLightDome in the level.
