If you’ve changed your CameraShakes to MatineeCameraShakes in 4.26, in 4.27 the MatineeCameraShake was moved to its own module: GameplayCamera. You’ll need to include that in your projects Build.cs, and update your includes
from:
#include <Runtime/Engine/Classes/Camera/CameraShake.h>
to
#include <GameplayCameras/Public/MatineeCameraShake.h>
Also noticed a few members need accessed or set via Getters and Setters, but the deprecated warnings messages give all the details there so should be easy enough for people to sort.
