Aspect Ratio getting stretched after packaging?

I set my in-game camera’s aspect ratio to 4:3, or 640 x 480, or 1.3333, whatever you want to call it. It’s supposed to have black bars on the sides, but instead the screen just gets stretched after I package the game, and it looks awful. When I play in the editor, it looks great and perfect, but after packaging, it gets stretched and looks awful. How do I fix this, and why is it happening? Thanks :slight_smile:
