Variables

  Type Name Description
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite float AutoPlaneShift Manually adjusts the planes of this camera, maintaining the distance between them.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite bool bAutoCalculateOrthoPlanes Automatically determine a min/max Near/Far clip plane position depending on OrthoWidth value
Public variable UProperty Category BlueprintReadWrite Transient uint32: 1 bCameraCutThisFrame True if we did a camera cut this frame.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite uint32: 1 bConsiderUnrenderedOpaquePixelAsFullyTranslucent Whether to only render exponential height fog on opaque pixels which were rendered by the scene capture.
Public variable UProperty Category, EditAnywhere, AdvancedDisplay BlueprintReadWrite bool bEnableClipPlane Enables a clip plane while rendering the scene capture which is useful for portals.
Public variable UProperty Category, EditAnywhere, AdvancedDisplay, Meta BlueprintReadWrite bool bEnableOrthographicTiling Render the scene in n frames (i.e TileCount) - Ignored in Perspective mode, works only in Orthographic mode when CaptureSource uses SceneColor (not FinalColor) If CaptureSource uses FinalColor, tiling will be ignored and a Warning message will be logged
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite uint32: 1 bOverride_CustomNearClippingPlane  
Public variable UProperty Category, EditAnywhere, AdvancedDisplay, Meta BlueprintReadWrite bool bRenderInMainRenderer Render scene capture as additional render passes of the main renderer rather than as an independent renderer.
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite bool bUpdateOrthoPlanes Adjusts the near/far planes and the view origin of the current camera automatically to avoid clipping and light artefacting
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite bool bUseCameraHeightAsViewTarget If UpdateOrthoPlanes is enabled, this setting will use the cameras current height to compensate the distance to the general view (as a pseudo distance to view target when one isn't present)
Public variable UProperty Category, AdvancedDisplay BlueprintReadWrite bool bUseCustomProjectionMatrix Whether a custom projection matrix will be used during rendering.
Public variable UProperty Meta bool bUseFauxOrthoViewPos  
Public variable UProperty Category, EditAnywhere, AdvancedDisplay BlueprintReadWrite FVector ClipPlaneBase Base position for the clip plane, can be any position on the plane.
Public variable UProperty Category, EditAnywhere, AdvancedDisplay BlueprintReadWrite FVector ClipPlaneNormal Normal for the plane.
Public variable UProperty Category, EditAnywhere BlueprintReadWrite TEnumAsByte< enum ESceneCaptureCompositeMode > CompositeMode When enabled, the scene capture will composite into the render target instead of overwriting its contents.
Public variable UProperty Category, EditAnywhere, AdvancedDisplay, Meta BlueprintReadWrite float CustomNearClippingPlane Set bOverride_CustomNearClippingPlane to true if you want to use a custom clipping plane instead of GNearClippingPlane.
Public variable UProperty Category, AdvancedDisplay BlueprintReadWrite FMatrix CustomProjectionMatrix The custom projection matrix to use
Public variable TObjectPtr< class UDrawFrustumComponent > DrawFrustum The frustum component used to show visually where the camera field of view is
Public variable UProperty Category, EditAnywhere, Interp, Meta BlueprintReadWrite float FOVAngle Camera field of view (in degrees).
Public variable UProperty Category, EditAnywhere, AdvancedDisplay, Meta BlueprintReadWrite int32 NumXTiles Number of X tiles to render. Ignored in Perspective mode, works only in Orthographic mode
Public variable UProperty Category, EditAnywhere, AdvancedDisplay, Meta BlueprintReadWrite int32 NumYTiles Number of Y tiles to render. Ignored in Perspective mode, works only in Orthographic mode
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite float OrthoWidth The desired width (in world units) of the orthographic view (ignored in Perspective mode)
Public variable UProperty Category, Interp, Meta BlueprintReadWrite float PostProcessBlendWeight Range (0.0, 1.0) where 0 indicates no effect, 1 indicates full effect.
Public variable UProperty Category, Interp, Meta FPostProcessSettings PostProcessSettings  
Public variable UProperty Category, EditAnywhere, Meta BlueprintReadWrite TEnumAsByte< ECameraProjectionMode::Type > ProjectionType  
Public variable TArray< TWeakPtr< ISceneViewExtension, ESPMode::ThreadSafe > > SceneViewExtensions Array of scene view extensions specifically to apply to this scene capture
Public variable UProperty Category, EditAnywhere BlueprintReadWrite TObjectPtr< class UTextureRenderTarget2D > TextureTarget Output render target of the scene capture that can be read in materials.
Public variable int32 TileID Which tile to render of the orthographic view (ignored in Perspective mode)
