Variables

  Type Name Description
Public variable bool bAdditionalViewFamily Indicates this view family is an additional one.
Public variable bool bCurrentlyBeingEdited Whether the scene is currently being edited, which can be used to speed up lighting propagation.
Public variable bool bDeferClear Used to defer the back buffer clearing to just before the back buffer is drawn to
Public variable bool bDrawBaseInfo Indicates whether, or not, the base attachment volume should be drawn.
Public variable bool bIsFirstViewInMultipleViewFamily Whether this view is the first of multiple view families rendered in a single frame.
Public variable bool bIsHDR When enabled, the post processing will output in HDR space
Public variable bool bIsMultipleViewFamily Whether this view is one of multiple view families rendered in a single frame.
Public variable bool bIsSceneTexturesInitialized  
Public variable bool bIsViewFamilyInfo  
Public variable bool bMultiGPUForkAndJoin If true then each view is not rendered using the same GPUMask.
Public variable bool bNullifyWorldSpacePosition Indicates whether the shader world space position should be forced to 0.
Public variable bool bOverrideVirtualTextureThrottle Whether to disable virtual texture update throttling.
Public variable bool bRealtimeUpdate Indicates whether the view family is updated in realtime.
Public variable bool bRequireMultiView True if scenecolor and depth should be multiview-allocated
Public variable bool bResolveScene If true then results of scene rendering are copied/resolved to the RenderTarget.
Public variable bool bThumbnailRendering Whether this view is for thumbnail rendering
Public variable bool bUsedDebugViewVSDSHS  
Public variable bool bWorldIsPaused GetWorld->IsPaused() && !Simulate Simulate is excluded as the camera can move which invalidates motionblur
Public variable float DebugDPIScale DPI scale to be used for debugging font.
Public variable EDebugViewShaderMode DebugViewShaderMode  
Public variable FDisplayInternalsData DisplayInternalsData For r.DisplayInternals (allows for easy passing down data from main to render thread)
Public variable FEngineShowFlags EngineShowFlags The new show flags for the views (meant to replace the old system).
Public variable FExposureSettings ExposureSettings Editor setting to allow designers to override the automatic expose.
Public variable uint64 FrameCounter Copy from main thread GFrameCounter to be accessible on render thread side.
Public variable uint32 FrameNumber Copy from main thread GFrameNumber to be accessible on render thread side.
Public variable float GammaCorrection Gamma correction used when rendering this family. Default is 1.0
Public variable int8 LandscapeLODOverride Override the LOD of landscape in this viewport.
Public variable FString ProfileDescription Optional description of view family for Unreal Insights profiling.
Public variable float * ProfileSceneRenderTime Optional tracking of scene render time in seconds, useful when rendering multiple scenes (such as via UDisplayClusterViewportClient) where the user may want a live breakdown of where render time is going per scene, which the stat system otherwise doesn't provide.
Public variable const FRenderTarget * RenderTarget The render target which the views are being rendered to.
Public variable FSceneInterface * Scene The scene being viewed.
Public variable ESceneCaptureCompositeMode SceneCaptureCompositeMode When enabled, the scene capture will composite into the render target instead of overwriting its contents.
Public variable ESceneCaptureSource SceneCaptureSource Which component of the scene rendering should be output to the final render target.
Public variable ESecondaryScreenPercentageMethod SecondaryScreenPercentageMethod  
Public variable float SecondaryViewFraction Secondary view fraction to support High DPI monitor still with same primary screen percentage range for temporal upscale to test content consistently in editor no mater of the HighDPI scale.
Public variable FGameTime Time The current time.
Public variable TArray< TSharedRef< class ISceneViewExtension, ESPMode::ThreadSafe > > ViewExtensions Extensions that can modify view parameters on the render thread.
Public variable EViewModeIndex ViewMode View mode of the family.
Public variable int32 ViewModeParam  
Public variable FName ViewModeParamName  
Public variable TArray< const FSceneView * > Views The views which make up the family.
Public variable int32 VirtualTextureFeedbackFactor Size in pixels of a virtual texture feedback tile.
