--- title: "VRayScene" canonical: "https://documentation.chaos.com/space/VRAYUNREAL/116557908/VRayScene" format: markdown --- 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 Supported Features Maya Importing vrscene files Cameras VRay Physical Camera Focus Distance; Target Distance; Field of view; Film gate; Focal length; Film Speed (ISO); F-number; Shutter speed(s^-1); Exposure; Custom White balance; Near Clipping Plane Geometry Triangle meshes VRayProxy - initial support, no animated meshes UV channels 0, 1, 2, 3 Initial support for displaced/smoothed meshes Pivot offset Lights V-Ray Dome light - Light - On/Off; Units - Default image; Multiplier; Color; Texture Sphere light - Light - On/Off; Color; Temperature; Units - Default image, Luminous power; Multiplier; Cast Shadows - On/Off Rectangle light - Enabled - On/Off; Light color; Temperature; Intensity multiplier; Units - Default image, Lumens; Directional; Shadows - On/Off Mesh light – Light - On/Off; Units - Default image; Multiplier; Color; Temperature; Invisible - On/Off; IES light - Enabled - On/Off; IES file; Cast shadows - On/Off; Color; Temperature; Intensity type - lumens Sun - Enabled - On/Off; Turbidity; Sky model - Hosek et al.
