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 Toolbar The V-Ray toolbar allows you to render using V-Ray’s Interactive renderer and bake lighting with   V-Ray Bake . From the V-Ray drop-down menu you can access the V-Ray frame buffer, open the  V-Ray Settings  tab, open the  V-Ray Project Settings  and open the  VRScene Export Options . From the V-Ray Bake drop-down you can access the  V-Ray Bake Settings  tab.  Button States The V-Ray button and V-Ray Bake button have five states depending on the process that is currently running: Button State Description Idle/Neutral  –   V-Ray is in idle mode, not processing or rendering the scene. Preparing  – V-Ray is preparing the scene for rendering. Meshes, textures, materials and lights are cached into memory. Rendering  – V-Ray is rendering the sceene. Click on the button to stop rendering at any time. Busy  – V-Ray is unloading resources and exits rendering. Finished  – V-Ray has reached the specified parameters in  V-Ray Settings . Idle/Neutral  – V-Ray is in idle mode, not processing or rendering the scene. Preparing  – V-Ray is preparing the scene for baking. Meshes, textures, materials and lights are cached into memory. Rendering  – V-Ray is baking the scene. Click on the button to stop rendering at any time. Busy  – V-Ray is unloading resources, exits rendering and processes lightmaps. Finished  – V-Ray has finished baking all atlases and lightmaps. V-Ray Assets Category The V-Ray Assets category in the  Modes  tab allows you to quickly create V-Ray related actors. V-Ray Light Dome  – A dome light (also considered an area light) creates light within a dome or spherical shape to create a traditional global illumination setup. This Light is frequently used to load HDRI environment images. 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. V-Ray Settings V-Ray Settings provide access to all render options available in V-Ray for Unreal. For more information, see the  V-Ray Settings  page. V-Ray Project Settings In V-Ray Project Settings you set global option for the entire Unreal project. For more information, see the  V-Ray Project Settings  page. V-Ray Bake Settings V-Ray Light Bake or just V-Ray Bake is the process of creating lightmaps with complex light interactions and diffuse interreflection using the V-Ray render engine and it's GI and Lighting calculations. For more information, see the  V-Ray Bake Settings  page. Import vrscene Dialogue The V-Ray Scene Import Options window appears when you are importing  .vrscene  files into Unreal. For more information, see the  Import a VRayScene  page. Exporting vrscene Dialogue The V-Ray Scene Export Options window appears when you export  .vrscene  files from Unreal.  For more information, see the  Exporting a VRayScene  page.
