Non-dynamic reflections would look better in darkened zones (tunnels, caves) if there was an option to override the globalEnviromentMap with a custom or a darker cubemap. Also dynamic reflections should adapt to the zone instead using the time of day lighting.
Hello again. Now I'm also wishing for an optional zone feature that forces AI traffic to turn on their vehicle headlights. I am aware that this thread is old, but I still want to make a reply rather than make a new thread called: "Request II: Trick AI cars to turn on their headlights in dark road tunnels like it's night time!". It's the law in most countries, so it should be an easy checkbox option, not a programming effort for map makers.
