Syntax

UCLASS (BlueprintType)  
class UMovieGraphSequenceDataSource : public UMovieGraphDataSourceBase

Remarks

The UMovieGraphSequenceDataSource allows using a ULevelSequence as the external datasource for the Movie Graph. It will build the range of shots based on the contents of the level sequence (one shot per camera cut found inside the sequence hierarchy, not allowing overlapping Camera Cut sections), and then it will evaluate the level sequence for the given time when rendering.

Variables

  Type Name Description
Protected variable TSharedPtr< MoviePipeline::FCameraCutSubSectionHierarchyNode > CachedSequenceHierarchyRoot  
Protected variable TSharedPtr< UE::MovieGraph::FMovieGraphSequenceTimeController > CustomSequenceTimeController Custom Time Controller for the Sequence Player, used to match Custom TimeStep without any floating point accumulation errors.
Protected variable UProperty Transient TObjectPtr< ALevelSequenceActor > LevelSequenceActor

Public function Virtual void

CacheDataPreJob ( const FMovieGraphInitConfig& InInitConfig
)

 Called when the Movie Graph Pipeline starts before anything has happened, allowing you to cache your datasource before making any modifications to it as a result of rendering.
