UMovieGraphRenderLayerSubsystem | Unreal Engine 5.6 Documentation

API > API/Plugins > API/Plugins/MovieRenderPipelineCore

The primary means of controlling render layers in MRQ. Render layers can be added/registered with the subsystem, then made active in order to view them. Collections and modifiers can also be viewed, but they do not need to be added to the subsystem ahead of time.

Functions

Public

Name	Remarks	Include Path	Unreal Specifiers

void ClearActiveRenderLayer()	Clears the currently active render layer and reverts its modifiers.	Graph/MovieGraphRenderLayerSubsystem.h	BlueprintCallable Category="Settings"
UMovieGraphRenderLayer * GetActiveRenderLayer()	Gets the currently active render layer (the layer with its modifiers applied).	Graph/MovieGraphRenderLayerSubsystem.h	BlueprintCallable Category="Settings"
const TArray< UMovieGraphRenderLayer * > & GetRenderLayers()	Gets all render layers which are currently tracked by the system.	Graph/MovieGraphRenderLayerSubsystem.h	BlueprintCallable Category="Settings"
void RemoveRenderLayer ( const FString& RenderLayerName )	Removes the render layer with the given name.	Graph/MovieGraphRenderLayerSubsystem.h	BlueprintCallable Category="Settings"
void Reset()	Clear out all tracked render layers and collections.	Graph/MovieGraphRenderLayerSubsystem.h	BlueprintCallable Category="Settings"
void SetActiveRenderLayerByName ( const FName& RenderLayerName )	Applies the layer with the given name.	Graph/MovieGraphRenderLayerSubsystem.h	BlueprintCallable Category="Settings"
void SetActiveRenderLayerByObj ( UMovieGraphRenderLayer* RenderLayer )	Applies the given layer.	Graph/MovieGraphRenderLayerSubsystem.h	BlueprintCallable Category="Settings"
