Public function Virtual Const bool Returning false disables the extension for the current frame in the given context.
Protected function Virtual Const bool Called if no IsActive functors returned a definitive answer to whether this extension should be active this frame.

PostRenderBasePassDeferred_RenderThread ( FRDGBuilder& GraphBuilder,
FSceneView& InView,
const FRenderTargetBindingSlots& RenderTargets,
TRDGUniformBufferRef< FSceneTextureUniformParameters > SceneTextures
)

 Called right after Base Pass rendering finished when using the deferred renderer.
Public function Virtual void Called right after Base Pass rendering finished when using the mobile renderer.
Public function Virtual void Allows to render content after the 3D content scene, useful for debugging
Public function Virtual void Allows to render content after the 3D content scene, useful for debugging
Public function Virtual void Called on render thread prior to initializing views.
Public function Virtual void

PrePostProcessPass_RenderThread ( FRDGBuilder& GraphBuilder,
const FSceneView& View,
const FPostProcessingInputs& Inputs
)

 Called right before Post Processing rendering begins
Public function Virtual void Called on render thread at the start of rendering, for each view, after PreRenderViewFamily_RenderThread call.
Public function Virtual void Called on render thread at the start of rendering.
Public function void

SetupView ( FSceneViewFamily& InViewFamily,
FSceneView& InView
)
