FMovieGraphAccumulationDOFPass

Movie Graph deferred render pass for aperture-sampled depth of field.

API > API/Plugins > API/Plugins/AccumulationDOF

Movie Graph deferred render pass for aperture-sampled depth of field.

This pass renders multiple aperture samples with off-axis projection matrices and accumulates them using GPU shaders to produce plausible DOF.

Camera parameters (focal length, aperture, focus distance) are read from the CineCameraActor being rendered by the sequence.

Variables

Name Type Remarks Include Path Unreal Specifiers
ApertureSampler TObjectPtr< UApertureSampler > Aperture sampler that handles sample rendering and accumulation. MovieGraphAccumulationDOFPass.h  
bCameraParamsInitialized bool Track whether we've initialized camera-dependent state. MovieGraphAccumulationDOFPass.h  
bInCapturePass bool Flag to indicate we're doing a capture pass (so AddViewExtensions knows to add the capture SVE). MovieGraphAccumulationDOFPass.h  
bInInjectionPass bool Flag to indicate we're doing the injection pass (so AddViewExtensions knows to add the injection SVE). MovieGraphAccumulationDOFPass.h  
CachedActualNumSamples int32 Effective telemetry values captured while render-layer modifiers are active. MovieGraphAccumulationDOFPass.h  
CachedCineCameraComponent TWeakObjectPtr< UCineCameraComponent > Cached reference to CineCameraComponent for SVE settings. MovieGraphAccumulationDOFPass.h  
CachedDOFComponent TWeakObjectPtr< UAccumulationDOFComponent > Cached reference to AccumulationDOFComponent (found in CineCameraActor). MovieGraphAccumulationDOFPass.h  
CachedEffectiveDOFSplatSize float   MovieGraphAccumulationDOFPass.h  
CachedMotionBlurFraction float Cached motion blur fraction from current frame's sample state. MovieGraphAccumulationDOFPass.h  
CachedSceneFringeIntensity float Cached SceneFringeIntensity from the first sample's SVE (blended with PP volumes). MovieGraphAccumulationDOFPass.h  
CaptureExtension TSharedPtr< FAccumulationDOFSceneViewExtension, ESPMode::ThreadSafe > Scene View Extension for capture passes (one per aperture sample). MovieGraphAccumulationDOFPass.h  
CurrentApertureSampleIndex int32 Current sample being rendered MovieGraphAccumulationDOFPass.h  
CurrentAxialCAWeight FVector3f RGB weight for current spectral band in axial chromatic aberration. MovieGraphAccumulationDOFPass.h  
CurrentFocusDistanceOverride float Focus distance override for axial CA (negative means no override). MovieGraphAccumulationDOFPass.h  
CurrentTileCount FIntPoint Tile grid locked at Setup time. MovieGraphAccumulationDOFPass.h  
CurrentTileIndex FIntPoint Active tile index for the current Render() iteration, used by helper functions. MovieGraphAccumulationDOFPass.h  
CurrentTileOverlappedPad FIntPoint Tile overlap pad in pixels for the current Render() iteration. MovieGraphAccumulationDOFPass.h  
InjectionExtension TSharedPtr< FAccumulationDOFSceneViewExtension, ESPMode::ThreadSafe > Scene View Extension for injection pass. MovieGraphAccumulationDOFPass.h  
InjectionStatesInitialized TSet< FIntPoint > Tracks which per-tile injection view states have had their camera-cut prime applied. MovieGraphAccumulationDOFPass.h  
InjectionViewStates TMap< FIntPoint, FSceneViewStateReference > Separate view state for injection renders, keyed per tile so the injection pass keeps its own temporal history per tile. MovieGraphAccumulationDOFPass.h  
SavedLUTSize int32 Saved LUT size before override (0 if not overridden). MovieGraphAccumulationDOFPass.h
