This page provides details on the V-Ray for Unreal UI and how it is integrated into the Unreal interface.


Overview

The V-Ray for Unreal toolbar gives you access to all of the settings and options available in V-Ray.

From the V-Ray drop-down menu you can access the V-Ray frame buffer, open the V-Ray Settings tab, open the V-Ray Project Settings and open the VRScene Export Options. From the V-Ray Bake drop-down you can access the V-Ray Bake Settings tab.

The V-Ray Assets category in the Modes tab allows you to quickly create V-Ray related actors.


 





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.

V-Ray Light Mesh

A Mesh light creates a light source from an object's surface area.

V-Ray Light Rectangle

A V-Ray specific light source object that can be used to create physically accurate area lights of different shapes.

V-Ray Physical Camera

Simulates a real-world camera with equivalent parameters such as f-stop, shutter speed, and lens focal length.

V-Ray Settings Environment

Control the color and texture for background in the viewport and also the color and texture used during GI and reflection/refraction calculations at render time.

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.
