Objective: Understand what light probes are and how to implement on your project.

Light Probes. Light Probes provide a way to capture and use information about light that is passing through the empty space in your scene. They are a coordination of lights that pick up baked lighting information and relay it to dynamic objects.

To create light probes right click the hierarchy > Light > Light Probe Group.

//they look like a network of dots

You need to spread the dots around the area, anywhere you want to acknowledge dynamic appearance and have light share other information with objects.

To be able to modify the probes select the edit light probes button on the inspector. This enables you to select individual probes.

Depending on the size of the area you can duplicate the selected probes and add new probes.

Doing this had created dynamic lighting that’s going to take static baked illuminants info and pass to dynamic objects.

One light probe can light an entire level made up of thousands of probes. This is cheaper for your game/program. Light sources are expensive and light probes can give you your desire effect for a lot less data.

Don’t be afraid to experiment with light probes, they are simple to set up and are relatively cheap. Mastering light probes will give you the ability to create a better atmosphere.
