struct FMovieSceneObjectCache

Remarks

Object cache that looks up, resolves, and caches object bindings for a specific sequence

Variables

  Type Name Description
Public variable FOnBindingInvalidated OnBindingInvalidated Invoked when a binding is either explicitly invalidated (as a result of a spawnable being spawned, or a binding override being added) or when a previously resolved binding becomes invalid
