Stealth 1.8.2 addon - S.T.A.L.K.E.R. Anomaly mod for S.T.A.L.K.E.R.: Call of Pripyat Added Description Changed formula for NPC's detection. It is now heavily based on light and distance. Added weight, outfit and crouch factors. Flashlights/headlamps/campfires are now giving visibility boost to enemy. Modified luminosity itself (a lot). For version: 1.5.1. WARNING: There might be some weird spikes in NPC visibility (happens in vanilla too) on DX9 and higher. Usually happens in houses (Dead city, Limansk are the maps where I've met it). This is most likely caused due to broken static lights and from what I heard require recompilation of maps (which isn't something I or anyone I know can do).
