Functions

	Name	Description
void	Blended ( TArrayView< UMovieSceneSection*..., TMovieSceneEvaluationTree< FMovieSc... )	Adds all active and non-empty sections to the evaluation tree.
void	Blended ( TArrayView< UMovieSceneSection*..., TMovieSceneEvaluationTree< FMovieSc..., FSectionSortPredicate Predicate )	As above, but with custom sorting for the sections before they're added to the evaluation tree.
void	HighPass ( TArrayView< UMovieSceneSection*..., TMovieSceneEvaluationTree< FMovieSc... )	Adds active and non-empty sections to the evaluation tree based on priority: top rows have priority over bottom rows, and overlapping sections have priority over underlapped sections.
void	HighPassCustom ( TArrayView< UMovieSceneSection*..., TMovieSceneEvaluationTree< FMovieSc..., FSectionSortPredicate Predicate )	Adds active and non-empty sections to the evaluation tree based on the priority defined in the given predicate.
void	HighPassCustomPerRow ( TArrayView< UMovieSceneSection*..., TMovieSceneEvaluationTree< FMovieSc..., FSectionSortPredicate Predicate )	Adds active and non-empty sections to the evaluation tree based on the priority defined in the given predicate.
void	HighPassPerRow ( TArrayView< UMovieSceneSection*..., TMovieSceneEvaluationTree< FMovieSc... )	Adds active and non-empty sections to the evaluation tree based on priority: overlapping sections have priority over underlapped sections.
void	PopulateNearestSection ( TArrayView< UMovieSceneSection*..., TMovieSceneEvaluationTree< FMovieSc... )	Runs the logic to populate empty ranges in the field with the nearest section
