--- title: "Exporting a VRayScene" canonical: "https://documentation.chaos.com/space/VRAYUNREAL/116557910/Exporting%20a%20VRayScene" format: markdown --- This page provides information about export .vrscene file with V-Ray for Unreal. Overview VRayScene allows for assets to be shared between all platforms that run V-Ray. UI Path ІІV-Ray toolbar drop-downІІ > Export vrscene Exporting a .vrscene A vrscene from the an Unreal project can be exported with in two ways: V-Ray toolbar VRScene Name – Specifies the name of the generated . vrscene  file. Export VRScene Path  – Directory where the . vrscene  file is saved. Default directory is < ProjectPath>\Content  Compress  – Compresses geometric information thus making the resulting . vrscene  file smaller. NEW Export Selected Only – Exports only selected actors in the scene to a . vrscene file. Option will be ignored when Light Bake option is enabled. Light Bake – Exports separate .vrscene files for every light map atlas. The number of generated .vrscenes depends on: Actor Light Map resolution Atlas resolution Actor count in the level When you export a .vrscene a .bat file is also created with the name specified in VRScene Name and in the directory set in Export VRScene Path . You can use the .bat file to render the exported .vrscene in standalone, outside of Unreal. Note that currently a .bat file will not be generated when Light Bake option is enabled and will not work for light bake atlas .vrscenes . V-Ray Bake Settings Export VRScene – Enables the export of a . vrscene file when the V-Ray Bake  button is clicked. Export VRScene Path – Directory where the . vrscene file is saved with the file name bake#.vrscene.
