I realized I have slightly better test shots of global illumination than the ones that got out a week ago. These are from only a day or two after the last shots.
This is the Cirrus again, with landing lights and strobes; you can see that all of the airplane's lights contribute dynamically to the lighting on the fuselage and doors as they move. (Yes, that is heat blur on the engine; the heat blur still needs a lot of tuning.)
This shows airplane-mounted lights interacting with custom scenery. In this case the standard Cirrus (with global lights attached) casts both strobe and multiple landing light spill on LOWI. One of the powerful results of global illumination is that we get correct lighting interaction between diverse content, including third party content.
Finally, this shows an airport beacon lighting a plane and vice versa. The global lights on the airport beacon are inside an animation group, making them "sweep" the airplane, which can in turn animate the airport beacon. With global illumination, there are no rules about who lights who.
