Reflection Probes vs Screen Space Reflections

In this scene, you can see that the marble floor does not have reflections. To get this effect you can use a reflection probe

• In the hierarchy right click and go to light => reflection probe

• Now you will move the probe to the area you want to use it and adjust the size to fill the area

• This will create a reflection on the floor

Reflection Probe is on the Left

• Another way to do this is through the use of screen space reflections. Screen space reflections is a post-processing effect that reuses screen space data to create reflections

This method will give much more detailed reflections and will look better overall.

So why not use screen space reflections all the time? Using screen space reflections is a very taxing way to create this effect. If you are creating something like a mobile game you should use reflection probes because they are a much less taxing way to create this effect. If you are creating a game for a console or pc that will be able to afford the cost of creating effects with screen-space reflections then it is a great option.
