Let there be light…or something like it
Light Probes in Unity
Like most things in video game development, proper lighting is an art. The more complex our scenes get the more a good lighting setup will impact just how good it looks.
When we light our scene we can choose between baked lighting and real-time lighting but both are very expensive and only impact static objects in our scene. But what about our dynamic objects?
That is where Light Probes come in, they are cheap ways to add volumes to our scene that can quickly calculate our lighting setup and apply that to the moving objects. This vastly speeds up our light setup and makes lighting mobile games much easier.
To add light probes we just need to Right Click in the Hierarchy and choose Light > Light Probe Group.
The inspector allows us to edit the probe, make more probes, etc. The more complex our scene lighting, the more probes we will need.
Light probes can be learned in more detail at the Unity learn website.
