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.

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.
