Will Baked Lights automatically update when new GameObjects are added into the Scene?

Baked lights in a Unity scene refer to lighting that has been pre-calculated and stored in textures or data files, which helps improve performance by eliminating the need for real-time lighting calculations. When new GameObjects are added to a scene, baked lighting does not automatically adjust to account for these changes. This is because baked lighting is static by nature; once it is generated, it remains fixed and does not respond to dynamic scene alterations.

To update the lighting, the scene must be re-baked. This ensures that all new GameObjects, along with their associated properties like materials and light interactions, are factored into the baked lighting data. Thus, the correct understanding is that once baked, lights will not adapt to modifications unless the baking process is renewed, solidifying the reason for the selected answer.
