In this video tutorial, I will show you step by step how to use Light Probes, how to set up them, and how they work.

The main use of light probes is to provide high quality lighting (including indirect bounced light (GI)) on moving objects in your scene.

Similar to lightmaps, light probes store “baked” information about lighting in your scene. The difference is that while lightmaps store lighting information about light hitting the surfaces in your scene, light probes store information about light passing through empty space in your scene.

Probe lighting is very performant at run time and has the added benefit that it is quick to precompute. But remember that more probes you have on your scene, the more performance they cost. Probe lighting is unsuitable for representing lighting across very large objects where lots of lighting variation could be expected.
