Actually non of your 4+ realtime solutions are really usable, they all are a work in progress or simply broken.
Please check your information source cause Uncharted 4 isn’t using lightmaps for his massive levels they are uisng Dynamic lighting, and
for Cryengine you are also wrong, cryengine dropped almost a year ago they’re LPV system and chnaged to Envoirement probes for GI.
Just found from a simple source about Uncharted 4, source http://www.trustedreviews.com/
“Exclusive to PS4, Uncharted 4 looks fantastic, with realtime shadowing and dynamic lighting put to good use in the demo.”
From my understanding you wont find a nextgen game which is using lightmaps, especially not for huge outdoor environments, it simply makes no sense, imagine the building times and the size of all your lightmaps…
