Creating Reflections Using “Reflection Probes” In Unity
When you are making objects in your scene that you want to reflect their surroundings, one easy way to do that is with “Reflection Probes”. You can add them to your scene within seconds to upgrade your scene’s visual quality/aesthetic and the objects within it.
To implement reflection probes into your scene all you have to do is right-click within the hierarchy and select “Light>Reflection Probe”. Then edit the “Bounding Volume” to encompass the area/object that you are trying to make reflective and done!
It is important to know that Reflection Probes are not as effective as Screen Space Reflections, but they are less costly to your system and thus are more effective to use on projects that will be facing limited memory such as mobile games.
