Overview

These features are supported by V-Ray for Unreal. Currently supported versions of Unreal Engine are 4.21.2, 4.22.3 and 4.23.1.

For best results when importing vrscene files make sure your scenes are authored and optimized for V-Ray GPU Next or V-Ray GPU 3.6.

All supported features from Unreal Engine are listed in the Rendering table below.

Only Render nodes for V-Ray Next are supported.

V-Ray for Unreal only supports normal maps in tangent space.

V-Ray for Unreal uses only the V-Ray Hybrid engine.
