Smooth Edges

Hello, i’m trying to create my first visualization in ue4, but the furniture corners and walls are too rough. Can you recommend me some setting’s for smooth corners please?

If you want rounded edges you’ll have to model rounded edges

I dont want to make rounded edges, but a simple and nice interior visualization with clean and smooth edges. As you can see in the picture, after build lighth and creating HighResShot 2, it creates edges that are not so smooth. In the picture, I gave a red color to the problem areas:
