>>712703343>why don't devs do this then?because real time lighting allows them to be lazy with level design and lets them change things at the last second if they want to
imagine your level designer decides to remove one large box from a level which had several objects beside it in the shaded side of it, what does that mean for real time lighting? nothing, or very little, real time in engine lighting will adapt to removing it in a matter of seconds
but what if lighting is baked in? good, now you have to rebake all the shadows that were affected by that box, all the AO maps for all the several object that were beside that box, as well as potentially rebaking the environment AO map of the entire area.
this is what we mean when we say baking light takes skill, not cause the act itself of baking it takes any skill at all, the skill is in carefully placing all the objects how you want them, careful level design and decoration planning so that everyhing is as you want it to be, and locked in, no room for second guessing your work at the last minute.
but with real time lighting, you can change the entire decorations of an entire map in a few minutes and you can do that even a week before the game goes gold, when it would have taken more than a month with baked lighting
