Precomputed lighting data

Unity can perform lighting calculations in advance, and save the results as lighting data. The process of performing lighting calculations in advance is known as baking, or precomputing. The Baked Global IlluminationA group of techniques that model both direct and indirect lighting to provide realistic lighting results. Unity has two global illumination systems that combine direct and indirect lighting.: Baked Global Illumination, and Realtime Global Illumination.
See in Glossary system and the Realtime Global Illumination system both precompute lighting data.
