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 Illumination system and the Realtime Global Illumination system (deprecated) both precompute lighting data.
