This is the documentation for Enlighten.
8. Light probe resolution
Enlighten automatically places light probes around actors that:
are lit by probes
have meshes
have the mobility Static
To see where the probes are, in the View Mode menu, choose Enlighten > Probes.
This shows the probes in the level.
The actors in this level use the default Enlighten probe resolution, which is sufficient for believable indirect lighting.In the Outliner, double-click the actor Props_Balcony_6 to focus on it.
Because the fire escape is not directly lit by the sun, it is lit only by indirect lighting sampled from probes. To make this easier to see, select Lighting Only.
