The Halifax did have curtains between the individual crew work stations in the forward section of the aircraft (including one between the navigator and bombardier in the nose), and so if as pilot you lean over and peer down into the passageway, you'll see that the radio operators curtain is closed, as is the one leading forward to the navigator and bombardier's positions. Having curtains there is authentic (and necessary, as there won't be enough polygons available to suitably model other compartments). But leading rearwards, aft of the flight engineer's station behind the pilot, we're going to have to assume that the crew decided they didn't want light coming up front in case anyone brewed some tea in the centre section, and jury rigged a curtain sealing off the fuselage interior.
I will try to make it so that a little light leaks around the curtains, so you'll know your crew is hard at work at their individual jobs as you fly the aircraft.
The flight engineer's station will not be as detailed as the pilot's, as you have to play the flight engineer's role only briefly during startup and shutdown; it's main use to the sim pilot, once flying, will be to monitor the fuel levels, and there'll be a camera view to do that.
