Also, if the engine can't handle dynamic lighting (kinda weird for a 3D cinematic RPG, but maybe there's a way to trick us into thinking the light is changing when it's not), then could it possibly do weather effects? Maybe having different or occasionally different weather after long rests could be good. There is such thing as sunshowers. It would give us more ambient effects and extinguish old fire patches, like at the Nautilloid or Waukeen's Rest after completing the burning inn quest.
Oddly, there’s only one weather effect in the game, and the way it’s implemented breaks immersion rather than adds to it. There’s a single cloud waiting to ambush your party outside the Blighted Village. Rain triggers if the party is in a specific zone, abruptly starting and stopping in a noticeably unnatural way.
I really like the suggestion of using weather to differentiate consecutive days. It would help sell the illusion of time, as well as add that extra bit of strangeness to the underdark (which has no weather) where time would seem to stand still compared to the surface.
