Hi , I’m looking at doing something similar at the moment, porting some of our Aruco code. I was wondering how you took control of the projection matrix so that it matches your calibrated instrinsic camera parameters? Last time I did something similar, I had to modify the engine itself (which is not an option now). Did you extend UGameViewportClient instead? UE4 really needs to expose some of these controls

There is no way to do that, you have to modify the engine. The plugin is set up for an “average” webcam, and don’t do any camera specific distortion / lens correction. I am also waiting for this to be exposed in the engine.
