Baking illumination and color

Baking transfers the illumination of baked objects into an image file (if you bake to textures) or data (if you bake to vertices) that you can later apply to objects. After baking, you can simplify the scene by removing lights, materials, and textures (shading networks), because the game engine renderer obtains color and illumination information from the baked image or the data produced. See Bake color and illumination to textures.
