Don't nod's Jusant was announced a couple of days back and it has
a demo that's out on Steam. While it doesn't specify an Unreal version it most certainly seems to be 5+ as it seems to be using Nanite, Lumen and virtual shadow maps:
Interesting to see those employed in the context of a more stylized art style. While I was able to spot some minor light leaking while playing the demo, overall the lighting looked very good. Surprisingly so even, as smooth surfaces with little texture detail tend to be a worst case scenario for GI systems.
