I am trying to make a scene that is largely mirrored and I ran a few test renders with the mirror part from one of the city block module sets as well as a test with the chrome-finished 1x2 tiles. The surface finish appears to be the same as the virtual image appears to be just as blurry no matter which I use. However, I'm pretty sure that the mirror piece is actually an effective mirror IRL and so should have a different finish that doesn't blur the reflection.

Thank you for everything!
