Thanks for the detailed explanation! What I come to realize is that everything that is not related to ultra realist graphics doesn't have great support by Unreal Engine. It was not until version 5.3 - if I'm not mistaken - that they fixed some very basic aspects of the ortographic camera like shadows.
But back to my question, so would your recommendation be to not change anything on the camera itself and leave it with the settings you have, and change everything I need on the scene capture component, right?
