Variables

  Type Name Description
Public variable FString AdditionalCommandLineArguments Additional command line arguments to pass to the external process when capturing

Protected variable Scalability::FQualityLevels CachedQualityLevels Cached quality levels
Protected variable TSharedPtr< ICaptureStrategy > CaptureStrategy Strategy used for capture (real-time/fixed-time-step)
Protected variable TMap< FString, FStringFormatArg > FormatMappings Format mappings used for generating filenames
Protected variable int32 FrameNumberOffset Frame number index offset when saving out frames.
Protected variable FMovieSceneCaptureHandle Handle Our unique handle, used for external representation without having to link to the MovieSceneCapture module
Public variable TObjectPtr< UMovieSceneImageCaptureProtocolBase > ImageCaptureProtocol Capture protocol responsible for actually capturing frame data
Public variable FSoftClassPath ImageCaptureProtocolType The type of capture protocol to use for image data
Public variable FString InheritedCommandLineArguments Command line arguments inherited from this process
Protected variable TOptional< FCaptureProtocolInitSettings > InitSettings The settings we will use to set up the capture protocol

Classes

  Type Name Description
Public class FOnCaptureFinished Event that is fired after we've finished capturing  

Constants

Name Description
MovieSceneCaptureUIName This name is used by the UI to save/load a specific instance of the settings from config that doesn't affect the CDO which would affect scripting environments.
