Camera Lens Effect

Adding camera lens effects is quite simple. You can use Unreal built-in blueprint node AddGenericCameraLensEffect to create a camera lens effect of a given class, node ClearCameraLensEffects to remove all camera lens effects, and node RemoveGenericCameraLensEffect to remove the given lens effect. All you need to do is to create a lens effect emitter class, and pass it into the node you want to call.
