The Screen Space Reflection effect creates subtle reflections that simulate wet floor surfaces or puddles. This technique produces lower quality reflections than using Reflection Probes or planar reflections, which create perfectly smooth reflections. Screen Space Reflection is an ideal effect to limit the amount of specular light leaking.
The Screen Space Reflection effect is tuned for performance over quality to make it ideal for Projects running on current-gen consoles and desktop computers. It’s not suitable for mobile development. Because it relies on the Normals G-Buffer, it is only available in the deferred rendering path.
Screen Space Reflection creates more detailed reflections than other methods such as Cubemaps or Reflection Probes, because GameObjects using Cubemaps for reflection cannot self-reflect, and Reflection Probe reflections are limited in their accuracy.
For more information on how to use Screen Space Reflections in Unity, refer to the Screen Space Reflections documentation in the Post Processing package.
