No shadows after baking lighting?

I’ve never had this problem before, so I’m confused as to why the shadows suddenly aren’t working. It appears to work on one of my objects (a laptop sitting on a table) but it does not work on my other objects (the table itself and a bench sitting in front of it). The lightmap resolution on the two meshes is 64, and the floor under them is the default Unreal Engine floor (the one you get when you make a new level and select “default”). I’m using the default directional light that comes with the level. Does anyone know why shadows aren’t showing up?

Most likely your lightmap resolution is too low
