Light-maps are no longer used.
Lighting is all real-time these days with rare minor exceptions.
That is not even close to true.
"Perfectly true!" I thought to myself. And then I tried to think of all the games recently that do use it, or that are coming out that make use of it, and came up a bit short to be honest.
I even looked at (recently released) the top sellers on steam at the moment: Rocket League, not so far as I can tell? (Edit: Maybe yes? I haven't played it) ARK: Nope. Homeworld Remastered: Nope. GoT Telltale: Yes. GTAV: Nope. CS GO: Yes. Witcher 3 : Nope. Polybridge: Nope.
So while it's still used certainly and by all means, I would say it is surprisingly, or perhaps because of the fanaticism for "open world" games unsurprisingly being phased out somewhat. Regardless Digitalfragment has some good links if OP is interested.
