Using Composure + Dynamic Post Processing

We are trying to use our camera lens model together with Composure.

Our lens model is applied to the output of a CineCameraActor using a dynamic PostProcess material (dynamic in the sense that the lens parameters are not constant, they might change every frame as new tracking data is received). Unfortunately, this post processing does not seem to be applied to the corresponding Composure output.

If I understand correctly, this happens because Composure does not use the original camera output but rather duplicates the camera perspective with a SceneCaptureComponent2D.

Is there a standardized way to replicate the post processing including parameters of the original camera in Composure?
