What are Light Probes used for?

Light Probes are utilized to sample baked lighting at specific points in a scene. They play a crucial role in enhancing the realism of dynamic objects by capturing the lighting information in the environment, which allows those objects to blend more naturally with the baked lighting of static geometry.

When static lighting information is baked into lightmaps, dynamic objects within the scene might not receive the right lighting unless Light Probes are employed. By sampling the lighting at various positions, the system can approximate how light would fall on moving objects in relation to the objects that have already been baked into the scene, thus ensuring a consistent visual appearance.

The other options pertain to different components of the rendering process. Generating lightmaps is a separate function that primarily focuses on static lighting. Rendering shadows involves different techniques that might not directly link to Light Probes. Meanwhile, adjusting light intensity is a separate property that controls how bright or dim a light source emits light, rather than how it is sampled at various points in the environment.
