Overview
The V-Ray for Unreal toolbar gives you access to all of the settings and options available in V-Ray.
V-Ray Toolbar
The V-Ray toolbar allows you to render using V-Ray’s Interactive renderer and bake lighting with V-Ray Bake. 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.

V-Ray Assets Category
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.
