"Realistically render nighttime environments" ? I was planning on staying out of these "discussions" but really, spend some time in the countryside in the night. even when it's winter (summer in Finland is silly bright since the sun barely goes below horizon even in the south and above the arctic circle it doesn't go down at all...) and there's no snow coverage yet (which again reflects a ton of moonlight) it's still easy to see where you're going and moving people can be seen 20m away easily. Someone walking on a grass (or other low vegetation) field is really easy to see for 100-150m distance they do not have woods or other dark and irrelugar background behind them from where you're looking, if they silhuet against the sky then they're even easier to see If there's heavy cloud cover then there's less moonlight, though near cities (if they still have lights, I have kept my distance from cherno etc) the city lights also add a lot on ambient light. So the current night system is IMO broken too, I did play some night missions in ArmA2 "proper" a longish while back and I think I recall it being pretty good then on the default brightness/gamma settings. The problem here I guess is that if we want proper "realistic" night on normal gamma settings then increasing gamma (and to some extend brightness) will allow players to see much better and only way around it is to lock the gamma/brightness adjustments (making just about everything that is slightly dark 100% black, killing all of the dynamic range the you see for real when walking in nighttime, is not the "realistic" way to go about it) So for realistic nights: 1. bring back the dynamic range (DR) 2. adjust the HDR lightning system so to emulate the way you eyes adjust to darkness, so if you use a flashlight or fire you weapon (muzzle flash...) you lose a lot of the DR (going back towards the "blind at night") and then gradually restore DR again (it's actually pretty quick to restore). Flares even though they're red (which as a color doesn't hurt you night-vision as much) are so bright that crossing your vision directly with a flare -> large loss of DR, as for chemlights I don't think I have used blue ones for real so can't say about that. Anyway I'm fairly sure Rocket knows all this already (AFAIUnderstand he's been in the military too [Finland has compulsory service for all adult males, so yes: been there, done that...]), just trying to educate those that think the current system is "realistic" somehow... Now, it might be that Rocket want to keep it this way for other reasons, but realism isn't one of them.
