The Amazing Power of Light Probes
Guide To Beautiful Games In Unity
Light Probes provide a way to capture and use information about light that is passing through the empty space in your scene. Light probes store “baked” information about lighting in your scene.
During run-time, dynamic objects can then receive values from surrounding Light Probes as the object moves through the world. This allows dynamic objects to receive local lighting in order to appear correctly integrated with surrounding lighting conditions.
To create a light probe group in your scene, go to Add > Light > Light Probe Group
After adding the light probe in your scene, you can expand it in the scene by duplicating the selected group or a new light probe in the scene.
We set the static objects as static so that they can store the global illumination which are then used by light probes to provide light to dynamic objects as well as static to appear correctly integrated with surrounding lighting conditions.
In this image, the cube and the walls are not illuminated properly even though there is a light source.
In this image, the objects are illuminated through light probes in the presence of baked light source.
