@yukinoh1989 Baking is used for cutting down on rendering calculations. Where backing is mostly used is in game development to fake things, for example like lighting where calculating ray tracing in real time is very costly and will slow down the game to a crawl, so you save that information out into a map where now the engine just has to display a texture and not actually perform any calculations. Or baking high resolution details to a low resolution mesh. There are many types of baking. More info.
