What function does a Light Probe primarily serve in a Unity game?

A Light Probe in Unity serves the important function of storing lighting data for dynamic objects in a scene. This data includes information about the color and intensity of light that reaches the probe from various sources. When dynamic objects—such as characters or movable props—pass near or interact with these Light Probes, they can sample this precomputed lighting information to accurately reflect their surroundings.

This enables dynamic objects to blend seamlessly with the static environment, thereby improving visual realism without requiring full dynamic lighting calculations for every object. By using Light Probes, developers can enhance performance while ensuring that dynamic objects receive appropriate lighting that complements their interactions with the scene.

The other provided options focus on different functionalities that are not the primary role of a Light Probe. For instance, Light Probes do not directly impact game physics, create shadow effects, or manage audio settings, as those are responsibilities typically handled by other components within Unity.
