Deprecated Variables

  Type Name Description
Protected variable UProperty Meta PRAGMA_DISABLE_DEPRECATION_WARNINGSFDistortionHandlerPicker DistortionSource_DEPRECATED This property has been deprecated. The handler picker is no longer used to identify a distortion handler. Use the LensDistortionHandlerMap to get a handler for the current LensModel.
Protected variable UProperty FVector OriginalCameraLocation_DEPRECATED This property has been deprecated. The LensDistortion component no longer tracks the attached camera's original location.
Protected variable UProperty FRotator OriginalCameraRotation_DEPRECATED This property has been deprecated. The LensDistortion component no longer tracks the attached camera's original rotation.

Deprecated Functions

  Type Name Description
Public function Const PRAGMA_DISABLE_DEPRECATION_WARNINGSFDistortionHandlerPicker This property is deprecated. Use GetDistortionSource() and SetDistortionSource() instead.
