Okay, after lots of testing, here is a patch that fixes all vanilla flare issues:
class CfgAmmo { class FlareCore; class FlareBase:FlareCore { intensity = 500000; }; class Flare_82mm_AMOS_White:FlareCore { intensity = 1000000; effectFlare = "FlareShell"; }; };
40mm flares inherit from FlareBase. From my tests 100k intensity (that RHS has) is nowhere close to OA or early A3 GL flare brightness, I tested 500k and it seems to be too bright it seems to be close to whatever original A3 had:
original A3:
500k intensity for 40mm flare (what I suggest to have):
250k intensity for 40mm flare (not enough, 100k is even less):
