Journal 52 — Using Reflection Probes versus Screen Space Reflections in Unity
Objective: To compare the use of reflection probes and screen space reflections in a scene.
In the example below from “The Great Fleece”, we can simulate the reflections on the floor .
To start, we can add a new light object called a reflection probe.
The reflection probe can be set to three different types: Baked, Custom, and Realtime.
For this example, we can increase the intensity as one of the settings.
We can edit the location to set the reflection probe close to the floor surface.
Next, we need to update the bounding volume to set the reflection space to the approximate room size.
As you can see from the bounding volume, when brought just below the floor, the reflections pop up!
One final adjustment is to select the box projection for the space, which is useful for improving the accuracy of reflections in indoor spaces.
As part of the Unity Post Processing Package, Screen Space Reflections creates reflective effects such as for wet, shiny, or mirrored surfaces, along with several other enhancements.
For additional information, you can refer to these post processing assets set up for “The Great Fleece” at itch.io.
