Interesting!!
I only jumped into D&D at 5th edition, so this will be very interesting to play with since I don't know the setting

Areas look really interesting too!
It does look like your lighting is not completely set up in the video? (Black shadows)
Might want to regenerate the lighting (Menubar > Level > Render all light probes).
Or fiddle with
Light probes and atmospheres in general.
In any case, keep up the awesome work

Sincerely,
Kevin
