    I'm using Unity 2017.4.15f1

    I've been trying to research a solution to this problem for a few days now and I've come to the conclusion that the settings "Box Size" & "Box Offset" do not change anything with how the reflection probe is baked or appears. In the picture below, you can see my problem. The actual projected reflection box is larger than the room, giving it a very distorted effect.

    Hey! If the room where you've placed your reflection probe is not perfectly square, sooner or later you will hit the limitation you are currently seeing. Reflections in realtime rendering are still tricky, especially with mirror surfaces.

    One way to mitigate this would be to setup a camera which looks to the opposite side of the room, and renders to a render texture. Then you can assign that texture to the mirror in your room to have perfect reflections. Keep in mind that this method is very expensive and should be used sparingly.
