VRayScene

This page provides information about .vrscene format in V-Ray for Unreal.

Overview

VRayScene allows for assets to be shared between all platforms that run V-Ray. It loads a previously saved .vrscene file into V-Ray for Unreal and supports rendering geometry, materials and lights.

For a step by step guide on how to import and use a .vrscene file, see the Intro Importing .vrscene QuickStart page.

For additional information about importing .vrscene in Unreal check the documentation here: Importing a VRayScene

For additional information about exporting a .vrscene out of Unreal check the documentation here: Exporting a VRayScene
