Variables

  Type Name Description
Protected variable bool bHasDefaultValue  
Protected variable bool DefaultValue  
Protected variable FMovieSceneKeyHandleMap KeyHandles This needs to be a UPROPERTY so it gets saved into editor transactions but transient so it doesn't get saved into assets.
Protected variable TArray< FFrameNumber > Times  
Protected variable TArray< bool > Values
